Answer:
I think the coefficient is 4
Answer:
Carbon monoxide + hydrogen ------> methanol
Explanation:
In writing a chemical equation, the substances which react together to form other substances are known as products and are usually placed on the left side of a the equation, whereas the substances that are formed by the reactants are known as products and are usually written on the right side of the equation. A forward pointing arrow is usually placed between the reactants and and products to show how the reaction proceeds from reactants to formation of products.
From the given equation, methanol is the product formed from the reactants carbon monoxide and hydrogen. Therefore, the equation will be:
carbon monoxide + hydrogen -----> methanol
Answer:
The heat of reaction is basically the energy that is being released and or absorbed when chemicals are transformed in a type of chemical reaction. However, the heat of reaction or also called reaction enthalpy is mostly or typically expressed as a molar enthalpy in kJ/mol and or as just a specific enthalpy in kJ/kg or kJ/L.

Answer:
A. How much decay happens in each flashlight
Explanation:
In an experiment, the DEPENDENT OR RESPONDING VARIABLE is the variable that responds to changes being made to another variable called Independent variable. It is the variable that is measured by an experimenter.
In this question, an experiment was carried out to research the effect of sunlight on plastic decay. Three plastic flashlights were used for this experiment in which one was placed in a dark closet (control), and the others were placed in light at different times or intervals. However, the variable being measured or assessed is the decay of each flashlight. This means that "HOW MUCH DECAY HAPPENS IN EACH FLASHLIGHT" is the dependent variable.
