Answer:

Plants use a process called photosynthesis to make food. During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch.

Answer:

Sun, water, caron dioxide.

Explanation:

They get there energy from those because photosynthesis the sun gives them that energy but the sun goes with water too because the sun and the water help it eat and produce its food and then the carbon is for it to breathe and thats how we have oxygen because the plants take in carbon and then they give out oxygen so thats why we need plants and plants need us.

How much heat is needed to raise the temperature of 7g of water by 18oC?
Oliga [24]
Specific heat of water, C = 4.18 J/g. °C
From question, Mass of water= 7g
Temperature difference = 180 degree Celsius

We know by formula,
Heat (Q)= c* m(mass) * T (change in temperature)
 So, Q= 4.18 J/g. °C *7g * 180 °C
         =5266.8 J

What else can the copper react with?
Jet001 [13]
Copper oxidizes in moist air
2Cu + CO₂ + O₂ + H₂O = (CuOH)₂CO₃

copper reacts with concentrated acids, for example, with nitric acid
Cu + 4HNO₃ = Cu(NO₃)₂ + 2NO₂ + 2H₂O

copper reacts with chlorine
Cu + Cl₂ = CuCl₂

copper reacts with oxygen when heated
2Cu + O₂ = 2CuO

How to equally balance CH4 + O2 → H2O + CO2 (Please show work)
grin007 [14]

Answer:

Balanced chemical equation:

CH₄ + 2O₂  →  2H₂O + CO₂

Explanation:

Chemical equation:

CH₄ + O₂  →  H₂O + CO₂

Balanced chemical equation:

CH₄ + 2O₂  →  2H₂O + CO₂

Step one:

CH₄ + O₂  →  H₂O + CO₂

C  = 1                          C = 1

H  =  4                        H = 2

O  = 2                         O = 3

Step 2:

CH₄ + 2O₂  →  H₂O + CO₂

C  = 1                          C = 1

H  =  4                        H = 2

O  = 4                         O = 3

Step 3:

CH₄ + 2O₂  →  2H₂O + CO₂

C  = 1                          C = 1

H  =  4                        H = 4

O  = 4                         O = 4

SEP math! Each day, the average person's
Lesechka [4]

Answer:

Quarts of blood = 72000

Quarts of urine = 720

Explanation:

<h3><u>Given</u>;</h3>
  • Each day, the average person's
  • kidneys filter around 200 quarts of blood.
  • About 2 quarts of urine is produced in the
  • process.
<h3><u>To </u><u>Find</u>;</h3>
  • In one year the average person's kidney filter quarts of blood and quarts of urine.

Here, we know that

1 year = 365 days

For blood

200 × 365 = 72000

For urine

2 × 365 = 720

Thus, The average person's kidney filters 72000 quarts of blood and 720 quarts of urine.
