The best unit to measure the length of an object is meters.

Answer: Option A

<u>Explanation: </u>

Length is defined as the distance covered by any object from one end to another end of the object. It can also be termed as single dimension of the object. It is a measuring variable and like all measuring variables, it also has SI unit. The SI unit to determine the length of any object is meter.

So among the given options, cubic meters can't be the correct unit for length because it has three dimensional variable while length is a single dimensional variable. Similarly, kilograms is the unit of weight or mass of any object and kilogram per cubic meter is for density of any object. Thus the best unit for measuring the object's length is meters.

According to the big bang theory, which statements are accurate about how the universe came to be? Check all that apply.
asambeis [7]

The term Big Bang defines that the Universe has expanded from the ancient hot and thick primary situation at some fixed time in the past.

Big Bang theory refers to the origin of the Universe. In the beginning, universe is very heavy and small hot ball of matter. It was a point no bigger than the head of a pin when all the things squished with each other and universe is expanded with huge explosion of energy. Due to expansion, it is cooled and results in the formation of Stars and galaxies. After sometime, atoms formed like helium and hydrogen.

Thus, statement (1), (3) and (4) is correct whereas statement (2) and (5) is incorrect.

CH4 + 202 → CO2 + 2H2O<br> How many grams of O2 needed to produce 36 grams of H2O?
Pavel [41]

Answer:

Mass = 64 g

Explanation:

Given data:

Mass of water produced = 36 g

Mass of oxygen needed = ?

Solution:

Chemical equation:

CH₄ + 2O₂       CO₂ + 2H₂O

Number of moles of water produced:

Number of moles = mass/molar mass

Number of moles = 36 g/ 18 g/mol

Number of moles = 2 mol

Now we will compare the moles of water and oxygen.

             H₂O       :          O₂

                2         :           2

Mass of oxygen:

Mass = number of moles × molar mass

Mass =  2 mol × 32 g/mol

Mass = 64 g
