yield.
O
B. None of these
C. Catalysts are important to industry to increase product yields
D. A reaction can be sped up by reducing the surface area of solid reactants.
Reset Selection
Answer:
c
Explanation: c
The statement that is true from the following is catalysts are important to the industry to increase product yields. The correct option is C.
What is a catalyst?Catalysts are substances that speed up or increase the rate of reaction. The biological catalysts are enzymes. Enzymes are made up of proteins, and they are used in the reaction to increase the yield in less time. Catalyst does not mix with the process and after the reaction.
There are many chemical catalysts like nickel and iron. These catalysts are used in chemical and manufacturing processes. They impact, accelerate, and promote the reaction to get different yields.
Thus, the correct option is C. Catalysts are significant to industry to increase product yields.

Where is the DNA stored in a cell?
Answer: nucleus
Explanation:
What could you change or add to your models based on what you have learned about molecules and phases so far?
Answer:Phase changes require either the addition of heat energy (melting, evaporation, and sublimation) or subtraction of heat energy (condensation and freezing). ... Changing the amount of heat energy usually causes a temperature change.
Explanation:
Answer: The answer is Phase changes require either the addition of heat energy (melting, and evaporation) or subtraction of heat energy (condensation and coldness). Changing the amount of heat energy usually causes a temperature change.
Explanation:
For example it can be like 98 degrees today and it can be like 66 degrees the next day. It causes the weather to change. Weather changes so much because the Earth is constantly spinning. Lands and water bodies heat up differently that cause constant atmospheric change. Also note that "seasons" are not the same as weather. Seasons have to do with the angle of the solar radiation we receive caused by the tilt of the Earth on it's axis.

What can scientists use to determine the relative order of events on the geologic timescale?
Answer:
Scientists use a geologic time scale to illustrate the order in which events on Earth have happened.
Explanation:
Scientists can use the geologic time scale to determine the order in which several events on Earth have happened or taken place.
What is a geologic timescale?The geologic time scale can be described as a representation of time based on the rock record of Earth and is a system of chronological dating that uses chronostratigraphy and geochronology.
The geologic time scale can be used by scientists to observe changes in the fossils by examing the oldest to youngest sedimentary rocks or layer by layer.
The geologic timescale also used relative dating to divide Earth’s past into many layers of time and utilized absolute dating to know the actual number of years ago that specific occurrences took place.
Relative dating does not show any specific dates but it allows us to know if a fossil or stratigraphic layer is older than another while Absolute dating methods provide more specific origin dates and timelines.

When the speed of the bottle is 2 m/s, the KE is kg m2/s2. When the speed of the bottle is 3 m/s, the KE is kg m2/s2. When the speed of the bottle is 4 m/s, the KE is kg m2/s2. When the speed of the bottle is 5 m/s, the KE is kg m2/s2. When the speed of the bottle is 6 m/s, the KE is kg m2/s2.
instructions
In this part of the experiment, you will be changing the speed of the bottle by dropping it from different heights. You will use the same mass, 0.250 kg, for each trial, so record this mass in Table B for each velocity. Then, calculate the expected kinetic energy (KE) at each velocity. Use the formula KE = mv2,
where m is the mass and v is the speed. Record your calculations in Table B of your Student Guide.
Answer:
Based on the given instructions, you need to calculate the expected kinetic energy (KE) at each velocity using the formula KE = mv^2, where m is the mass and v is the speed. The mass is given as 0.250 kg.
Table B: Calculation of Kinetic Energy (KE)
Table B: Calculation of Kinetic Energy (KE)
Speed (m/s)Mass (kg)KE (kg m^2/s^2)20.2500.50030.2500.75040.2501.00050.2501.25060.2501.500
To calculate the kinetic energy at each velocity, multiply the mass (0.250 kg) by the square of the velocity.
For example, when the speed of the bottle is 2 m/s: KE = (0.250 kg) * (2 m/s)^2 = 0.250 kg * 4 m^2/s^2 = 1.000 kg m^2/s^2
Perform similar calculations for the other velocities and record the results in Table B.
Answer:
Explanation:mass of the bottle in each case is M = 0.250 kg
now as per given speeds we can use the formula of kinetic energy to find it
1) when speed is 2 m/s
kinetic energy is given as
2) when speed is 3 m/s
kinetic energy is given as
3) when speed is 4 m/s
kinetic energy is given as
4) when speed is 5 m/s
kinetic energy is given as
5) when speed is 6 m/s

What happens to air pressure and amount of oxygen as the altitude increases in Earth's atmosphere? 1. Air pressure decreases, while the amount of oxygen increases. 2. Both air pressure and the amount of oxygen increase. 3. Air pressure increases, while the oxygen decreases. 4. Both air and oxygen decrease.
Answer:
As altitude increases in Earth's atmosphere, both air pressure and the amount of oxygen decrease.
At sea level, the air pressure is about 1013.25 millibars (mb) and the concentration of oxygen is about 21%. As you go higher in the atmosphere, the air becomes thinner and less dense, so the air pressure decreases. At the same time, the concentration of oxygen also decreases because there is less air overall to contain oxygen molecules.
This is why it is harder to breathe at high altitudes, such as on a mountain. The air is less dense, so there are fewer oxygen molecules per breath and the body has to work harder to get enough oxygen.
Answer:4: Both Air and Oxygen decrease.
Explanation:This is in accordance with Henry's law. As pressure decreases solubility of gases decreases. Air pressure decreases as we altitude increases and the decrease in oxygen level is the consequence ,
What can you infer from the fact that metals are good conductors of electricity?
A.electrical appliances made of metal are dangerous B Most electrical wiring is made of metal C all non-metallic objects, like water and the human body, are poor electrical conductors D metals also make good insulators
Answer:
B
Explanation:
makes sense
Metals are good conductors of electricity that's why most electrical wiring is made of metal.
What are metals?Metals are those elements which are mainly present in the s-block and d-block of the periodic table and they are opaque and lustrous elements.
Most important property of the metals is that they are good conductor of electricity due to the formation of ion (cation) property. And because of only this property metals are used in the electrical wiring materials.
So, we conclude that most electrical things are made up of metal.
