Which of the following locations will most likely have the highest rate of evaporation?
A. South Pole
B.Sahara Desert
C Atlantic Ocean
D Amazon rainforest

Time taken = 3 hours

Given

speed : 75 mph

distance : 225 miles

Required

time taken

Solution

An equation of constant velocity motion  

[tex]\large {\boxed {\bold {d = v \times \: t}}}[/tex]

d = distance = m  

v = speed = m / s  

t = time = seconds  

Input the value :

t = d : v

t = 225 miles : 75 miles/hour

t = 3 hours

Answer:

20 g of copper (II) oxide, CuO

Explanation:

The balanced equation for the reaction is given below:

CuO + 2HCl —> CuCl₂ + H₂O

From the balanced equation above,

1 mole of CuO reacted to produce 1 mole of CuCl₂.

Next, we shall determine the number of mole of CuO needed to produce 0.25 mole of CuCl₂. This can be obtained as follow:

From the balanced equation above,

1 mole of CuO reacted to produce 1 mole of CuCl₂.

Therefore, 0.25 mole of CuO will also react to produce 0.25 mole of CuCl₂.

Finally, we shall determine the mass of 0.25 mole of CuO. This can be obtained as follow:

Mole of CuO = 0.25 mole

Molar mass of CuO = 64 + 16

= 80 g/mol

Mass of CuO =?

Mole = mass /Molar mass

0.25 = mass of CuO /80

Cross multiply

Mass of CuO = 0.25 × 80

Mass of CuO = 20 g

Therefore, 20 g of copper (II) oxide, CuO is needed for the reaction.

The term mole is defined as the amount of substance of a system which contains as many elementary entities. A mole of Br₂ and a mole of CH₂Br₂ have a mass of 1g each. Therefore, option A is correct.

The term mole is defined as the amount of substance of a system which contains as many elementary entities.

1 mole is equal to 6.023 × 10 ²³ molecules.

One mole of any substance is equal to 6.023 × 10²³ units of that substance such as atoms, molecules, or ions. The number 6.023 × 10²³ is called as Avogadro's number or Avogadro's constant.

The mole concept can be used to convert between mass and number of particles.

A mole of Br₂ and a mole of CH₂Br₂ have a mass of 1g each. Because one mole of substance is equal to 6.023 × 10 ²³ molecules.

Thus, option A is correct.

Answer:

To name an ionic compound, you simply need to find the names  of the cation and anion present in the compound and make sure to revise the ends of metal names as needed. First, write out the name of the metal, followed by the name of the non-metal with its new ending.

Explanation:

Write the name of the cation, and then write the name of the anion, changing the ending to "-ide" if it's a single element and leaving it as it is if it's a polyatomic ion.

Answer:

3. Structural features

Answer:

24.06 g of CO₂

Explanation:

The balanced equation for the reaction is given below:

CH₄ + 2O₂ —> 2H₂O + CO₂

Next, we shall determine the mass of O₂ that reacted and the mass of CO₂ produced from the balanced equation. This can be obtained as follow:

Molar mass of O₂ = 2 × 16 = 32 g/mol

Mass of O₂ from the balanced equation = 2 × 32 = 64 g

Molar mass of CO₂ = 12 + (2×16)

= 12 + 32

= 44 g/mol

Mass of CO₂ from the balanced equation = 1 × 44 = 44 g

SUMMARY:

From the balanced equation above,

64 g of O₂ reacted to produce 44 g of CO₂.

Finally, we shall determine the mass of CO₂ produced by the reaction of 35 g of O₂. This can be obtained as follow:

From the balanced equation above,

64 g of O₂ reacted to produce 44 g of CO₂.

Therefore, 35 g of O₂ will react to produce = (35 × 44)/64 = 24.06 g of CO₂.

Thus, 24.06 g of CO₂ were produced from the reaction.
