Answer:

Explanation:

Start by writing water as HOH

Ca(OH)2 +CO2 = CaCO3+ HOH

Next pay attention to the CO2 going to CO3

We need an oxygen.

Fortunately that is provided by the (OH)2

Now we have

Ca(OH)2 + CO2 ==> CaCO3 + HOH

and believe it or not, that is balanced as it is

The left side has 1 Ca. So does the right side

The Left side has 1 C.  So does the right side.

The left side has 2 H. So does the right side

The left side has 2 oxygens (in Ca(OH2)) + 2 oxygens in CO2

So the equation is balanced.

PLEASEEEE HELP I WILL GIVE 30 POINTS Cobalt
Ymorist [56]

Answer:

Iron: Fe

Co: Cobalt

Na: Sodium

Tin: Sn

P: Phosphorus

F: Flourine

Fe: Iron

Magnesium: Mg

Uranium: U

Ca: Calcium

Carbon: C

Lead: Pb

Ag: Silver

Zn: Zinc

Ni: Nickle

----------------

There is honestly no right answer for this but here is what I would put:

Atomic mass increases as you go from left to right. If you look at the periodic table, it would be between Sn and Sb. It would bet here because Sn is 118 and Sb is 121. Basing it off of Antimony and putting it in group 15, the properties are that it is metallic and is a poor conductor of heat. I would call it Stin, which would be shortened to St.

Uranium-238 decays very slowly.its half-life is 4.47 billion years.
coldgirl [10]
13.4 billion years is 3 times of the half-life, 4.47 billion years. So the Uranium-238 will go through three times of half decay. So the remain percentage will be 50%*50%*50%=12.5%.

A solution of pH 5 is diluted 100 times. Find the pH of the resulting solution.
liq [111]
First, we calculate of the concentration of the H+ ions in the solution from the pH given. Then, calculate the new concentration after dilution. Calculation are as follows:

pH = -log[H+]
5 = -log[H+]
[H+] = 1 x 10^-5 M

M1V1 = M2V2
<span>1 x 10^-5 M (V1) = M2(100V1)
</span>M2 = 1 x 10^-7

pH =  -log[<span>1 x 10^-7</span>]
pH = 7
