The cells split up into two to repair the damaged cell so it should be A.
The object with dimensions 
and with mass 250.6 g will have a density equal to 
.
<h3>
<u>Explanation:</u></h3>
<u>Given:</u>
Dimensions of the object =
length = l = 5.54 cm
width = w = 10.6 cm
height = h = 199 cm
Mass of the object = m = 250.6 g
<u>Formula:</u>
The relation between density, mass and volume of any object is given by:
Since volume of an object with length (l), width (w) and height (h) [assuming a rectangular object] can be defined as,
Density of the object is 
Answer:blue blue blue
Explanation:
Just answered it and got it right
630g
Explanation:
firstly the equation has to be balanced. 2H2+o2>2H2o.
finding the mole of hydrogen?
mole = 70/2 which is equal to 35 mole of hydrogen.
35 mole of hydrogen is equal to the mole of water.
finding the mass of water=?
35=mass/18
mass= 35*18=630g of water
Answer:
3.6g
Explanation:
2 moles of water gives 1 mole of oxygen
2(h2o)=1(o2)
2(molar mass of h2o)=1(molar mass of oxygen molecule)
2(18)=1(16×2)
36=32
3.6=x
cross multiply
3.6×32=36× x
115.2=36x
x=115.2÷36
x=3.6g
