The reaction would produce bubbles of gas.
We can prepare 3-5 test tubes of acid with increasing concentrations. Then, we add antacid tablets to each and note the time taken for the tablet to dissolve and stop producing bubbles. The lesser the time taken, the greater the rate of reaction.
Explanation:
Percentage ethylene by weight = 57%
Percentage propylene by weight = 43%
Suppose in 100 grams of polymer:
Mass of ethylene = 57 g
Mass of propylene = 43 g
Moles of ethylene = 
Moles of propylene = 
1 mole = 
molecules/ atoms
Units of ethylene = 
Units of propylene = 
a) Fraction of ethylene units:
b ) Fraction of propylene units:
The substance that releases the greatest amount of ions will have the greatest attractive forces within its solution, resulting in a reduced freezing point.
K₂SO₄ yields 3 ions
NH₄I yields 2 ions
CoCl₃ yields 4 ions
Freezing points:
CoCl₃ < K₂SO₄ < NH₄I
Answer:
On genes within chromosomes
Explanation:
-The fur pattern is a genetic trait whose instruction is carried in the DNA's base sequence.
-These instructions are organized into genes and each gene is only responsble for the making of a functional product.
-Hence, the instructions are stored on genes within chromosomes.
Answer:
A physicist
Explanation:
Physics is that aspect of science that deals with nature and matter in relation to energy. Electricity is a source for energy
