The specific heat capacity the substance is calculated using the below formula

Q(heat) = Mc delta T
Q =1560 cal
m(mass) 312 g
delta T (change in temperature ) = 15 c
C= specific heat capacity=?

by making c the subject of the formula
c=Q/m delta T
= 1560 cal/ 312g x 15 c = 0.33 cal/g/c (answer B)

This equation shows a ____ refer to this summary equation of photosynthesis to complete the sentences about chemical bonds and r

coldgirl [10]

The balanced chemical equation representing the process of photosynthesis is:

$6 CO_{2} +12H_{2}O-->C_{6}H_{12}O_{6}+6O_{2}$

The reactants in the process of photosynthesis are $CO_{2}$ and H $H_{2}O$ and the products of the reaction are glucose $C_{6}H_{12}O_{6}$ and oxygen $O_{2}$ . Oxygen is the nonpolar covalent gas which is released in the process of photosynthesis. The reactant $CO_{2}$ is a nonpolar covalent gas while the other reactant water $H_{2}O$ has polar covalent O-H bonds.

In the balanced chemical equation, the number of each type of element must be equal on both sides of the reaction.
