Answer:
Molecules change speed based on temperature and state of matter. The warmer they are, the faster they move and vice versa. Solids are at a lower temperature than gases and liquids, which means the molecules are moving slower, and hold together better, also explaining why solids aren't malleable.
Answer:
Tests for unsaturation involves addition across the multiple bonds in the unsaturated compound.
Explanation:
In organic chemistry, we define an unsaturated compound as any compound that contains a double or triple bond. These multiple bonds are also known as pi bonds.
There are two major tests for unsaturation which shall both be discussed here.
The first test for unsaturation is by the use of bromine water. The unknown sample is passed through a solution of bromine water which normally appears reddish brown. The bromine water becomes decolorized due to addition of bromine across the multiple bond. This is a standard test for unsaturation.
Secondly, unsaturated compounds decoulourize a solution of potassium permanganate when passed through it. This alone can not be used as a distinctive test for unsaturation.
Propenoic acid will give a positive test to the both reagents showing that it contains multiple bonds, in this particular instance, a double bond.
Like mitosis, meiosis is a form of eukaryotic cell division. However, these two processes distribute genetic material among the resulting daughter cells in very different ways. meiosis gives rise to four unique daughter cells, each of which has half the number of chromosomes as the parent cell. Because meiosis creates cells that are destined to become gametes (or reproductive cells), this reduction in chromosome number is critical — without it, the union of two gametes during fertilization would result in offspring with twice the normal number of chromosomes!
Answer:
105
Explanation:
round 104 to the nearest whole number...since 7 is greater than 5 4 goes up..but if 7 is less than 5,4 remains the same
Answer is: quantity of sulfur is 13 tons.
Chemical reaction: S(s) + O₂(g) → SO₂(g).
From chemical reaction: n(S) : n(SO₂) = 1 : 1.
n(S) = n(SO₂); amount of substance.
m(S) ÷ M(S) = m(SO₂) : M(SO₂).
m(S) : 32 g/mol = 26 t : 64 g/mol.
m(S) = (32 g/mol · 26 t) ÷ 64 g/mol.
m(S) = 13 t = 13000 kg; mass of sulfur.
