1.11g of methane CH4 is burned in a bomb calorimeter containing 1000 grams of water. The initial temperature of water is 24.85 degrees Celsius. The specific heat of water is 4.184 J/g degrees Celsius. The heat capacity of the calorimeter is 695 J/degrees Celsius. After the reaction the final temperature of the water is 35.65 degrees Celsius. Calculate the heat absorbed by the water. Then calculate the heat absorbed by the calorimeter.

Rob measures the solubility of three different salts in water at 22°C. Which type of graph should he use to display his data? bar graph line graph histogram scatterplot

Answers

The best graph Rob can use to show his data is a scatter plot. A scatter plot shows a relationship between two sets of data in this case the solids and their respective solubility. A scatter plot is very specific in showing how one variable is affected by another variable.

Answer:

bar graph

"Enzymes help to achieve the equilibrium faster but cannot changethe thermodynamic
equilibrium constant. Why?"

Answers

Equilibrium constant Kc is defined as the concentration of products over reactants raised to the the powers of its respective molar ratios in of the balanced chemical reaction.
A catalyst by definition is a compound able to catalyse a reaction while being chemically unchanged in the process. The catalyst works by lowering the activation energy by providing an alternative pathway of lower activation energy.
The is no value in the equation whereby activation energy will affect the equilibrium constant.
To know the speed where the reaction reaches equilibrium we need to look at the rate equation also known as Arrhenius equation,
K= Ae^(-Ea/RT)
Here we can see with the lowering of Ea ( activation energy ) the rate constant rises causing the reaction to reach equilibrium quicker.

Final answer:

Enzymes cannot change the thermodynamic equilibrium constant of a reaction because they do not alter the free energy difference between the reactants and products.

Explanation:

Enzymes are biological catalysts that speed up chemical reactions by lowering the activation energy required for the reaction to occur. They achieve this by providing an alternative reaction pathway with a lower activation energy. However, enzymes cannot change the thermodynamic equilibrium constant of a reaction.

The thermodynamic equilibrium constant is a measure of the ratio of products to reactants at equilibrium. It is determined by the difference in free energy between the reactants and products. Enzymes, although they accelerate the rate at which equilibrium is reached, do not alter the free energy difference between the reactants and products. Therefore, they cannot change the equilibrium constant.

An experiment produced 0.10 g CO2, with a volume of 0.056 L at STP. If the accepted density of CO2 at STP is 1.96 g/L, what is the approximate percent error?

Answers

According to the accepted density of CO2, we can get that 0.10 g CO2 has a volume of 0.10/1.96=0.051 L (theoretical value). The percent error = (0.056 - 0.051)/0.051 * 100% = 9.80%.

Why carbon is a basic thing to classify as organic and inorganic compounds?​

Answers

Answer:

To answer, all living organisms contain carbon-based compounds, which classifies them organic.

Simply, carbon dioxide, is an example of an inorganic compound since it does not contain both carbon and hydrogen. Alternatively, one molecule of carbon dioxide contains one atom of carbon and two atoms of oxygen.
