Answer:
m/s
Explanation:
One 'm' and one 's' in the numerator and the denominator 'cancel out' and you are left with m / s
Answer:
bleaching powder is actually a mixture of calcium chloride, calcium hydroxide and calcium hypochlorite. hence it is not a single salt. It is not completely soluble in water as it composed of heavy calcium salts, which are known to be insoluble in water.
Answer:
D
Explanation:
It is higher in the air, so it will fall faster then the other apples.
Following the composition by mass, the molecular formula of monosodium glutamate would be
The empirical formula can first be derived such that:
C = 51/12 = 4.25
H = 4.778/1 = 4.77
O = 37.8/16 = 2.36
N = 8.29/14 = 0.59
Na = 13.60/23 = 0.59
Dividing by the smallest (0.59):
C = 7
H = 8
O = 4
N = 1
Na = 1
Hence, the empirical formula would be
Molar mass of empirical formula = 12x7 + 8x1 + 16x4 + 14 + 23
= 195
Recall that: , ()n = molecular formula
Where n = molar mass/empirical formular mass
Molar mass/empirical formular mass = 169/195
= 0.87
≈ 1
Thus, () x 1 =

Answer: Law of Conservation of Matter
-------
The amount of matter in a chemical process always remains constant inside a system. When matter is conserved, that means it stays the same, which is why it is called the law of conservation.
