Answer: It is important for an equation to be balanced because if it is not then the reactants won't match the products.
Explanation: I don't know if you will understand this but here:
Let's say you're cooking eggs, you're reactants so to speak would be 3 eggs and 1 tablespoon of oil so you put it together using heat and a pan. Your products have to match what you have in the beginning. You cannot have an equation that looks like this
Reactants = 3eggs + 1Tbsp oil ---pan/heat---> 6eggs + 1 cup of oil
You cannot get something from what you don't have. The number of how much of an element you have must be the same of both sides of the equation.
Answer:Electrons are atoms that are magnetic
Explanation:All atoms have electrons
Answer:
Boron would have a
+
3
charge.
Explanation:
Boron has an atomic number of
5
. For an atom to be an ion, it wants to have full electron shells with the "minimum number" (this is hard to explain). So that means that boron would either want
2
electrons or
10
electrons. Of course, it would be easier to have
2
electrons from
5
electrons, so there it will lose
3
electrons, and would have a final charge of
+
3
.
Answer:
The equilibrium concentration of P in the pond is 0.034 g/m³
Explanation:
Given that mass = 49.9 g
1 day = 24 hr
mass per hours;
Mass in = (49.9 g / day) * (1 day /24 hr
)
= 2.079 g/hr
Mass out = 0
Mass out due to sunlight = k 
V
Given, half life = 3.4 h
From first order reaction; k , rate constant = ln2/t, half time
ln 2= 0.693, V= volume
k = 0.693 / t half = 0.693 / 3.4 = 0.2038 hr⁻¹
putting all values in the expression k V ;
Mass out due to sunlight = k V
= Mass in hr / kV
= 2.079 g/hr / ( 0.2038 hr⁻¹ x 300 m³ )
= 0.034 g/m³
