What can u infer about Mimas and Tethys moons

1 answer:

5 0

<span>Scientists with NASA's Cassini mission have spotted "Pac-Man" images on moons of Saturn, Mimas & Tethys. The image in Mimas was seen in the year 2010, while in Tethys in the year 2011. The pattern appears in thermal data taken by Cassini's infrared spectrometer, with the warmer areas making up the Pac-Man shape. </span>

How would one convert 36 yd to centimeters (2.54 cm = 1 in)

ValentinkaMS [17]

I would go yards to feet, feet to inches, inches to centimeters. So 36 yards is 108 feet. There are 12 inches in a foot so 1,296 inches in 108 feet. Multiply that by 2.54 centimeters to get 3,291.84 centimeters in 36 yards.

Calculate the morality for the following<br> 10.5 kg of Na2 SO4. 10H2O in 18.60 L

Serggg [28]

Answer:

1.75M

Explanation:

The problem deals with finding the molarity of the given compound.

The compound is:

Na₂SO₄.10H₂O

Mass of the compound = 10.5kg = 10500g

Volume of the compound = 18.6L

Molarity is the number of moles of solute in a solution;

Molarity = $\frac{number of moles }{volume}$

Number of moles = $\frac{mass}{molar mass}$

Molar mass of Na₂SO₄.10H₂O = 2(23) + 32 + 4(16) + 10[2(1) + 16]

= 322g/mol

Now;

Number of moles = $\frac{10500}{322}$ = 32.6mole

So;

Molarity = $\frac{32.6}{18.6}$ = 1.75M

2 AgNO3(aq) + CaCl2(aq) -----> 2 AgCl(s) + Ca(NO3)2(aq)

yan [13]

5.732 grams of AgCl is formed when 0.200 L of 0.200 M AGNO3 reacts with an excess of CaCl2.

Explanation:

The balanced equation:

2 AgNO3(aq) + CaCl2(aq) -----> 2 AgCl(s) + Ca(NO3)2(aq)

data given:

volume of AgNO3 = 0.2 L

molarity of AgNO3 = 0.200 M

atomic weight of AgCl= 143.32 gram/mole

from the formula, number of moles can be calculated

Molarity = $\frac{number of moles}{volume in litres}$

number of moles of AgNO3 = 0.04

From the reaction:

2 moles of AgNO3 reacts to form 2 moles of AgCl

0.04 moles of AgNO3 reacts to form x mole of AgCl

$\frac{2}{2}$ = $\frac{x}{0.04}$

= 0.04 moles of AgCl is formed

mass of AgCl formed is calculated by multiplying number of moles with atomic mass of AgCl

mass of AgCl = 0.04 x 143.32

= 5.732 grams of AgCl is formed.

How many grams of water are produced from the combustion of 45.2 g of

Zina [86]

Answer:

101.56 of H₂O

Explanation:

The balanced equation for the reaction is given below:

CH₄ + 2O₂ —> CO₂ + 2H₂O

Next, we shall determine the mass of CH₄ that reacted and the mass of H₂O produced from the balanced equation. This is illustrated below:

Molar mass of CH₄ = 12 + (4×1.01)

= 12 + 4.04

= 16.04 g/mol

Mass of CH₄ from the balanced equation = 1 × 16.04 = 16.04 g

Molar mass of H₂O = (2×1.01) + 16

= 2.02 + 16

= 18.02 g/mol

Mass of H₂O from the balanced equation = 2 × 18.02 = 36.04g

SUMMARY:

From the balanced equation above,

16.04 g of CH₄ reacted to produce 36.04 g of H₂O.

Finally, we shall determine the mass of water, H₂O produced by the reaction of 45.2 g of methane, CH₄. This can be obtained as illustrated below:

From the balanced equation above,

16.04 g of CH₄ reacted to produce 36.04 g of H₂O.

Therefore 45.2 g of CH₄ will react to produce = (45.2 × 36.04)/16.04 = 101.56 g of H₂O.

Thus, 101.56 of H₂O were obtained.
