Answer:
d.
Explanation:
i was think b at first but that doesnt really explain how it gets to the circulatory system so d because without the the regulation of the heart rate and oxgen rich blood the muscular system can do absolutely nothing
Answer:
Na2SO4
Explanation:
In the crisscross method, we can write the correct formula for an ionic compound by crossing over the numerical value of each of the ion charges to now serve as the subscript of the oppositely charged ion. Subsequently, the signs of the charges are dropped and the correct formula of the ionic substance is obtained.
For sodium sulphate;
Na ^+ SO4^2-
By crisscrossing and dropping the signs to obtain the subscripts we now have;
Na2SO4
You can harm ur self if you dont know variables . Bcs the values of variables should limit.
I'm not sure but for those who can help:
<u>Skeleton equation</u>: It's neutralization because acid+base.
HCl + NaOH => H2O + NaCl
We are given that the specific heat of water is 4.18 J / g
°C. We know that the molar mass of water is 18.02 g/mol, therefore the molar
heat capacity is:
molar heat capacity = (4.18 J / g °C) * 18.02 g / mol
<span>molar heat capacity = 75.32 J / mol °C</span>
