  • Volume=10ml
  • Density=1.5g/ml

\boxed{\sf Density=\dfrac{Mass}{Volume}}

\\ \sf\longmapsto Mass=Density\times Volume

\\ \sf\longmapsto Mass=1.5(10)

\\ \sf\longmapsto Mass=15g

4. If the earth were to heat up by 3 degrees, approximately how much would the sea level rise?
Ksju [112]

The sea level would rise by some 50 meters.

Explanation:

If the earth's temperature increases by 3 degrees the north and south pole would experience the ice melt at high speed.

The life will get difficult on the plains.

The extinction of some species will happen.

The sea level would rise by 50 meters. The increased sea level will cause depletion of habitat from plants and animals.

The floods will occur, land erosion, soil for agriculture land will get contaminated with the salt.

Justin B. Believes that the temperature lowering during the fall months is what causes the color of the leaves to change. He set
Taya2010 [7]

Answer:

This question is incomplete, the remaining part of the question is:

What is the control group, independent variable and dependent variable?

Control group: Plants placed in 80 degree rooms

Independent variable: Change in temperature

Dependent variable: Change in color of leaves

Explanation:

The independent variable in a scientific experiment is the variable that the experimenter controls or manipulates in order to bring about a change in the dependent variable. In this experiment, the variable manipulated by Justin B is the TEMPERATURE CHANGE.

On the other hand, a variable is said to be dependent if it is the variable that responds to a change made to the independent variable or rather it is the outcome. In this experiment, Justin B is trying to see the outcome on the color change in leaves when exposed to a low temperature, hence, COLOR CHANGE IN LEAVES is the dependent variable.

Control group of an experiment is the group that receives no experimental treatment. It is the group the experimenter considers normal and hence is comparing with his experimental group. In this experiment, Justin B believes the leaves change color in a low temperature, hence, he placed some plants in a lower temperature (60 degree) in order to compare them with when the plants are placed in a higher temperature (80 degree). As far as this experiment is concerned, the plants placed in 80 degrees temperature are believed by Justin B not to undergo color change, hence, they are the CONTROL GROUP while the group he placed in 60 degrees temperature are what he is interested in, making them the EXPERIMENTAL GROUP

How many grams are there in 7.5x10^23 molecules of H2SO4
horsena [70]
Moles of H2SO4= 7.5x10^23/ 6.02x10^23 = 1.25 (3sf) moles of H2SO4

Mass of 1 mole of H2SO4= 98.1g

Therefore mass of 7.5x10^23 molecules of H2SO4= 122.63g

Marcia is given an incomplete chemical equation that includes the number of nitrogen atoms present in the products of the reacti
Anna [14]

Answer: There would have to be three nitrogen atoms in the products. The law of conservation of matter states that the amount of substance before a reaction occurs  should be the same as the amount of substance after the reaction.

Explanation: This is the EXACT sample answer from the test, just reword it if you want. ^
