The specific heat capacity of the metal is calculated using the following formula
Q(heat)= MC delta T
Q= 1495 j
c= specific heat capacity =?
M(mass)=319 g
delta T = change in temperature = 66-55 =11 c
by making c the subject of the formula
C=Q /M delta T
c= 1495 j/ 319 g x 11 c =0.426 j/g/c
The bonds between C and O are double bonds, because Carbon has to make 4 bonds in prefer to satisfy the octet rule and have 8 electrons in its outer shell. There are 2 double bonds
O=C=O
Ans: Elements in the same period have the same number of electron shells.
Answer:
4.858 g
Explanation:
Start with the formula
density = 
density = 1.98 g/mL
volume = 2.45 mL
mass = ??
rearrange the formula to solve for mass
(density) x (volume) = mass
Add in the substitutes and solve for mass
1.98 g/mL x 2.45 mL = 4.858 g
Answer:
Compared to early humans our brains seemed to have increased in size, and part of the cause may be because of things like Climage change, ecology and social competition
