how do humans benefit from photosynthesis

Answers

Equally importantly, photosynthesis is the source of oxygen and also removes carbon dioxide from our atmosphere. Oxygen is required for cellular respiration, the process by which food is broken down into energy. Thus, human beings are also solely dependent on photosynthetic plants for their oxygen requirements.

Answer:

Explanation:

Without photosynthesis there would be no oxygen in the earth's atmosphere and we wouldn't be here!

25cm3 of a 0.4M sodium hydroxide solution was diluted into 250cm3 of water. What is the molarityof the resultant solution.

Answers

Answer:

0.04 M

Explanation:

From the question given above, the following data were obtained:

Initial volume of solution (V1) = 25 cm³

Initial Molarity of solution (M1) = 0.4 M

Final volume of solution (V2) = 250 cm³

Final Molarity of solution (M2) =?

We can obtain the final Molarity of the solution by using the dilution formula as illustrated below:

M1V1 = M2V2

0.4 × 25 = M2 × 250

10 = M2 × 250

Divide both side by 250

M2 = 10/250

M2 = 0.04 M

Therefore, the resulting molarity of the diluted solution is 0.04 M

500 mL of He at 98 kPa expands to 750 mL.

Answers

500 mL of He at 98 kPa expands to 750 mL. Find P2.

P₂ = 65.3 kPa

Further explanation

Given

V₁=500 ml

P₁=98 kPa

V₂=750 ml

Required

P₂

Solution

Boyle's Law  

At a constant temperature, the gas volume is inversely proportional to the pressure applied  

[tex]\rm p_1V_1=p_2.V_2\\\\\dfrac{p_1}{p_2}=\dfrac{V_2}{V_1}[/tex]

Input the value :

[tex]\tt P_2=\dfrac{P_1.V_1}{V_2}\\\\P_1=\dfrac{98.500}{750}\\\\P_2=65.3~kPa[/tex]

What part does uplift play in the rock cycle?
A. It pulls rocks deep into Earth.
B. It pushes rocks up towards Earth's surface.
C. It breaks rocks into sediment.
D.It decreases pressure on buried rocks.

Answers

Answer:

Sometimes forces act to pull sections of the Earth's crust apart. At other times they are forced together. All this movement can cause rocks that were once underground to be brought up to the Earth's surface. This process is called uplift.

A 30 gram ball is at rest. Next, a force pushes the ball to the north for 2.5 seconds and the ball accelerates for a rate of 0,70 m/s/s. How fast is the ball going after the 2.5 seconds of acceleration? For credit, who work in detail

Answers

Answer:

1.75m/s or 6.3km/hr

Explanation:

here,

acceleration (a) = 0.7m/s^2

mass (m) = 30g

time (t) = 2.5s

initial velocity (u) = 0m/s

final velocity (v) = ?

now,

v = u + at

or, v = 0 + 0.7 * 2.5

hence, Final velocity (v) = 1.75 m/s

if u want to convert to km/hr

then,

1.75 * 3.6 (we know that 1m/s = 3.6km/hr)

= 6.3km/hr

A scientist thinks he found a new metal, so he published a paper about this metal. About 1 week after the scientist published the paper, you noticed a problem with the paper the scientist wrote. You noticed that this metal was not a new metal. In fact, this metal was discovered years ago. You determined this when you saw the atomic emission spectrum. As you read the article, you remembered that each atomic emission spectrum is unique to each element and the atomic emission spectrum matched one that was already discovered. Using the techniques from Chemistry, you ran a Flame Test with a piece of the metal (the metal is safe to use) that you had shipped to you. You found the metal turned the flame yellow. What metal did you have in your possession?

calculate the molar mass of cacl2

Answers

Answer:

[tex]\boxed {\boxed {\sf 110.98 \ g/mol}}[/tex]

Explanation:

The molar mass is the mass of a substance in grams per mole.

To find it, add the mass of each element in the compound. These masses can be found on the Periodic Table.

The compound given is:

[tex]CaCl_2[/tex]

The compound has 1 Ca (calcium) and 2 Cl (chlorine).

 

Mass of Calcium

The molar mass of calcium is 40.08 g/mol There is only one atom of Calcium in CaCl₂, so the number above is what we will use.

Mass of Chlorine

The molar mass of chlorine is 35.45 g/mol There are two atoms of chlorine in CaCl₂, therefore we need to multiply the molar mass by 2. 35.45 * 2= 70.9 g/mol

Molar Mass of CaCl₂

Now, to find the molar mass, add the molar mass of 1 calcium and 2 chlorine. 40.08 g/mol + 70.9 g/mol =110.98 g/mol

The molar mass of CaCl₂ is 110.98 grams per mole.
