Dr.Okoh has a steel beam with a volume of 35cm to the third power and a mass of 1040g. Find the density
Answers
Answer:
The answer is
29.7 g/cm³Explanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} [/tex]
From the question
mass of steel beam = 1040 g
volume = 35 cm³
The density of the steel beam is
[tex]density = \frac{1040}{35} \\ = 29.714285...[/tex]
We have the final answer as
29.7 g/cm³Hope this helps you

Identifying Physical and Chemical Properties
Answers
Ques: how to identify physical or chemical properties
Ans: you can identify them by their properties. make sure that it matches its property. but you must know the physical and chemical properties . i will give an example .so how to identify boiling of eggs and changing of water into ice. Physical properties
-it can be reversed back
-it is temporary change
-no new substance is formed
chemical properties
-it cannot be reversed back
-it is permanent change
-new substance is formed
now boiling of eggs matches all property of chemical change so it is chemical change. changing of water to ice matches all property of physical change so it is physical change.

Calcium oxide is made from the thermal decomposition of calcium carbonate: CaCO3 CAO + CO2
a) Calculate the maximum mass of calcium oxide that could be formed from heating 500 g of calcium
carbonate.
Answers
Answer:
Explanation:
n CaCO3 = mass / m.wt
= 500 /( 40 + 12 + 16x 3)
= 5 mole
n CaO = 5 moles ( from the balanced equation we have 1:1 moles )
mass of CaO = nCaO X m.wt
5 x( 40 +16 )
= 280 grams

EMERGENCY PLEASE HELP DUE IN 5 MINS!!! would your mass and weight differ on the Moon? The gravitational force of the Moon is one-sixth the gravitational force on Earth.
Answers
Answer:
Our weight on the moon is less than it would be on Earth due to a difference of the strength of gravity on the moon. The moon's gravitation force is determined by the mass and the size of the moon. ... This means that if you went to the moon you would weigh less, even though your mass stays the same!
Explanation:
The mass and weight of a person would be less on the moon on the earth because the gravitational force on the moon is less than that on the earth.
What is gravitational force?Gravitational force is the one by which all things pull onto the ground. It pulls everything towards itself. Gravity is present everywhere, but not in the same amount.
Gravity defines the weight of an object. On Earth, the weight is an object would be higher, than the planet, like Mars and the moon. The earth revolves on its axis and around the sun due to gravitational force.
The moon has a smaller mass than the earth and its pulling gravitational strength is also less, which is 1/6th of the earth.
Thus, Due to the moon's lower gravitational pull than the earth's, a person would have a lower mass and weight on the moon.
