What makes water H2O polar molecule ​

Chemistry
1 answer:
leva [86]3 years ago
8 0

☁️ Answer ☁️

Water (H 2 O) is polar because of the bent shape of the molecule.

☁️

Water (H 2 O) is polar because of the bent shape of the molecule. The shape means most of the negative charge from the oxygen on side of the molecule and the positive charge of the hydrogen atoms is on the other side of the molecule. This is an example of polar covalent chemical bonding.

saul85 [17]

Answer:

84.8%

Explanation:

Step 1: Given data

Bob measured out 1.60 g of Na. He forms NaCl according to the following equation.

Na + 1/2 Cl₂ ⇒ NaCl

According to this equation, he calculates that 1.60 g of sodium should produce 4.07 g of NaCl, which is the theoretical yield. However, he carries out the experiment and only makes 3.45 g of NaCl, which is the real yield.

Step 2: Calculate the percent yield.

We will use the following expression.

%yield = real yield / theoretical yield × 100%

%yield = 3.45 g / 4.07 g × 100% = 84.8%

The radioisotope potassium-40 decays to argon-40 by positron emission with a half-life of 1.3 Ã 109 yr. A sample of moon rock wa
Aloiza [94]

Answer:

4.66 x 10^8 yr

Explanation:

The age of the rock can be calculated using the equation:

ln (N/N₀) = - kt    where N is the quantiy of radioisotope decayed and N₀ is the initially quantity present of the radioisotope; k is the decay constant, and t is the time.

Now from the data , we have 78 argon-40  atoms for every 22 potassium-40 atoms, we can deduce that originally we had 22 + 78 = 100 atoms of potassium-40 so this is our N₀.

When we look at the equation, we see that k is unknown, but we can calculate it from the half-life which is given by the equation:

k =  0.693/ t half-life = 0.693/ 1.3 x 10⁹ yr = 5.33 x 10⁻¹⁰ yr⁻¹

Now we are in position to answer the question.

ln ( 78/100 ) =  - (5.33 x 10⁻¹⁰ yr⁻¹ ) t

- 0.249 = - 5.33 x 10⁻¹⁰ yr⁻¹  t

0.249/ 5.33 x 10⁻¹⁰ yr⁻¹  = t

4.66 x 10^8 yr
