on the periodic table it shows the molecular weight of all the elements and what you do is add all the numbers together:
CaCl2=40.08+35.45x2=110.98g/mol
*Ca(NO3)2=40.08+14.01x2+16x6=164.1g/mol
*Ca(OH)2=40.08+16x2+1.008x2=74.096g/mol
CaSO4=40.08+32.06+16x4=136.14g/mol
BaCl2=137.33+35.45x2=208.23g/mol
*these 2 require you to distribute the 2 into each of the elements.

Explanation:

A sample of nitric acid contains both H3O ions and NO3 ions. This sample has a pHvalue of 1.

Write a name of the positive ion present in this sample.

Answers

Answer : The name of positive ion present in this sample is, hydronium ion.

Explanation :

For formation of a neutral ionic compound, the charges on cation and anion must be balanced.

The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.

Ion : An ion is formed when an atom looses or gains electron.

When an atom looses electrons, it will form a positive ion known as cation.

When an atom gains electrons, it will form a negative ion known as anion.

As per question, hydronium ion or hydrogen ion is having an oxidation state of +1 called as $H_3O^(+)$ or $H^+$ cation and nitrate ion $NO_3^(-)$ is an anion with oxidation state of -1.

Thus they combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral $HNO_3$ .

Hence, the name of positive ion present in this sample is, hydronium ion.

. The density of gold is 19.32 g/mL. A U.S. $5.00 gold coin has a diameter of 1.62 cm and a thickness of 0.085 cm. The price of gold is currently $53.90 per gram. What is the value of the gold in the coin. V = π r2 h.

Answers

Answer:

$182 is the value of the gold in the coin

Explanation:

Diameter is 2r, the ratio of the coin is = 1.62cm / 2 = 0.81cm

Following the formula of the volume of the coin:

V = π r² h

V = π*(0.81cm)²*0.085cm

V = 0.172cm³ = mL

As the density of the gold is 19.32g/mL, the mass of 0.1752mL of gold is:

0.1752mL * (19.32g / mL) =

3.385g is the mass of the coin

As the price of the gold is $53.90 / g, the value of the gold in the coin is:

3.385g * ($53.90 / g) =

$182 is the value of the gold in the coin

Final answer:

To find the value of the gold in the coin, calculate its volume using the formula for the volume of a cylinder. The value of gold in the coin is $185.37.

Explanation:

To calculate the value of gold in the coin, we need to find its volume first using the formula for volume of a cylinder:

$V = \pi r^2h.$

The radius (r) of the coin is half its diameter, so it is 0.81 cm. The height (h) is 0.085 cm. Plugging in these values, we can find the volume of the coin. Next, we calculate the mass of the gold in the coin using its density and the volume we just calculated. Finally, we multiply the mass by the price per gram of gold to find the value of the gold in the coin.

The volume of the coin is:

$V = \pi (0.81 cm)2(0.085 cm)$

= 0.178 cm3.

The mass of the gold is:

m = density x volume

= 19.32 x 0.178

= 3.443 g.

The value of the gold in the coin is the value as -

= mass x price per gram

= 3.443 g x $53.90/g

= $185.37.

Which subatomic particle will be attracted by a positively charged object?(1) proton (3) electron
(2) neutron (4) positron

Answers

The subatomic particle which will be attracted by a positively charged object is: Choice 3: Electrons.

By law of electricity; like charges repel while unlike charges attract.

In essence, the subatomic particle which will be attracted to a positively charged object is a negatively charged particle.

Since, protons are positively charged, neutrons have no charge, positrons are positively charged but electrons are negatively charged,

The subatomic particle which will be attracted by a positively charged object is; Electron.

(1) Protons have a positive charge, so will be repelled by other positive charges
(2) Neutrons have no charge, so won't be affected by positive charges
(3) Electrons have a negative charge, so will be attracted by a positive charge
(4) Positrons have a positive charge, so will be repelled by other positive charges

The answer is (3)
