Find the mass of 3.21 x 10^-2 Nickel
Karo-lina-s [1.5K]

Answer:

1.88 g

Explanation:

n(moles) = mass/molar mass

mass = moles x molar mass of nickel

mass = 3.21x10^-2 x 58.69

mass = 1.883949 grams

mass = 1.88 g (2dp)

Hope this helps :)

7. When solid carbon reacts with oxygen gas to produce carbon dioxide gas, woul the triangle H value be on the reactant or produ
garik1379 [7]

When solid carbon reacts with oxygen gas to produce carbon dioxide gas. the deltaH (enthalpy change ) value is negative .DeltaH would be on the product side of the equation.

<h3>What is enthalpy change? </h3>

In a thermodynamic system, energy is measured by enthalpy. Enthalpy is a measure of a system's overall heat content and is equal to the system's internal energy plus the sum of its volume and pressure.

Knowing whether q is endothermic or exothermic allows one to characterise the relationship between q and H. An endothermic reaction is one that absorbs heat and demonstrates that heat from the environment is used in the reaction, hence q>0 (positive). For the aforementioned equation, under constant pressure and temperature, if q is positive, then H will also be positive. In a similar manner, heat is transferred to the environment when it is released during an exothermic reaction. Thus, q=0 (negative). Therefore, if q is negative, H will also be negative.

A chemist measures the energy change Delta H during the following
Ann [662]

Answer: 1) endothernic

2) Yes absorbed

Explanation:

Decomposition is a chemical reaction in which one reactant gives two or more than two products. All decomposition reactions are endothermic reactions as energy is absorbed to break the bonds.

Endothermic reactions are defined as the reactions in which energy of the product is greater than the energy of the reactants. The total energy is absorbed in the form of heat and \Delta H for the reaction comes out to be positive.

Exothermic reactions are defined as the reactions in which energy of the product is lesser than the energy of the reactants. The total energy is released in the form of heat and \Delta H for the reaction comes out to be negative.
