In this equation, what should be the coefficients of the reactants and products? I2 + O2 → I4O9

Answers

I am thinking that you are asking for the balanced equation for this chemical reaction. In order to balance this, you have to count each element where the elements in the reactants side and the product side should have equal number of molecules. The balanced reaction is as follows:

2I2 + 9/2O2 → I4O9

A material will float on the surface of a liquid if the material has a density less than that of the liquid. Given that the density of water is approximately 1.0 g/mL, will a block of material having a volume of 1.2 x 10^4 in^3 and weighing 350 lb float or sink when placed in a reservoir of water? [I just don't want the answer, I'd like to know how to solve this, please.]

Answers

Density is defined as the ratio of mass to volume of a substance.

The density of water is generally known to be 1.0 g/mL. Substances that are less dense than water will float on water while substances that are denser than water will sink in water.

We have to calculate the density of the block material in units of g/ml.

Volume of the block = $1.2 x 10^4 in^3$ = 19.66 mL

Mass of the block = 350 lb = 158757 g

Density of the block = $(mass)/(volume)$

Density of block = $(158757 g)/( 19.66 mL)$

= 8075.13 g/mL

Hence the block material will sink in water.

Given:
density of water is approximately 1.0 g/mL
block of material
volume of 1.2 x 10^4 in^3
and weighing 350 lb

Required:
Which will float

Solution:
D = M/V where D is density, M is mass and V is volume

convert 1.2 x 10^4 in^3 into mL
1.2 x 10^4 in^3 (16.39 mL/ 1 in3) = 196,980 mL

convert 350 lb into grams
350 lb (454 grams/1 lb) = 158,900 grams

D = M/V = 158,900 grams/ 196,980 mL
D = 0.807 g/mL

The block will float in water because it is less dense than water

State, in terms of subatomic particles, how an atom of C-13 is different from an atom of C-12

Answers

C-12 and C-13 are isotopes of the element carbon. Since they are both of the same element, they have the same number of protons. The number that follows the C indicates the number of neutrons. Isotopes are variations of the element with different number of neutrons. C-12 shows that that variation of carbon has 6 protons and 6 neutrons for a total mass of 12. C-13 shows that it has 6 protons but 7 neutrons for a total mass of 13
