Type the correct answer in the box. Express your answer to three significant figures. Calcium nitrate reacts with sodium phospha

6.07 grams is the theoretical yield of calcium phosphate (Ca₃(PO₄)₂).

<h3>How we calculate mass from moles?</h3>

Mass of any substance can be calculated by using moles as:

n = W/M, where

W = required mass

M= molar mass

Given chemical reaction is:

3Ca(NO₃)₂ + 2Na₃PO₄ → 6NaNO₃ + Ca₃(PO₄)₂

From the stoichiometry it is clear that:

3 moles of Ca(NO₃)₂ = produce 1 mole of Ca₃(PO₄)₂

Given mass of Ca(NO₃)₂ = 96.1g

Mole of Ca(NO₃)₂ = 96.1g/164g/mol = 0.5859moles

So, 0.5859 moles of Ca(NO₃)₂ = produce 0.5859×1/3 = 0.0196 moles of Ca₃(PO₄)₂

Required mass of Ca₃(PO₄)₂ will be calculated by using moles as:

W = 0.0196mole × 310g/mole = 6.07 grams

Hence, 6.07 grams is the theoretical yield of calcium phosphate.

which type of chemical reaction occurs faster at equilibrium the formation of production from reactants or that of reactants fro

Degger [83]

Answer :-

None of the forward reaction or backward reaction will be faster at equilibrium as

definition of equilibrium is that phase in which the rate of formation of product from reactant and rate formation of reactant from product is equal

and hence , both will be form at equal rate !!

A student observes that a popcorn kernel has a hard coat. He places the kernel in a moist paper towel and observes it for severa

Ierofanga [76]

Answer: Water inside the seed coat creating a pushing force, breaking the seed coat.

Explanation:

Seed germination can be defined as the process by which a new plant emerge out from a seed. The radicle is the first emerging part from a seed and it develops into a root and the plumule is the second emerging part and it develops into a shoot. The light, water, adequate temperature, and soil are the factors that are necessary for seed germination.

According to a given situation, the popcorn kernel will receive the moisture necessary for the germination process, the water will imbibe into the seed coat creating pressure inside the seed and which will cause the seed coat to break and the new plant parts or seedling will emerge out of the seed coat.
