Calculate 1.23 m x 0.89 m and give your answer with the correct number of significant figures?
Answers
Answer:
1.1m that what I got and it said it was right
The calculation of the given figure to one significant figure is[tex]1.1 m^{2}[/tex]
Significant figures can be regarded as a number of digits that is present in a particular value.Given 1.23 mAnd 0.89 m
If we multiply we have[tex]( 1.23*0.89) = 1.0947[/tex]
Since, there is no definite significant figure given, I will assume one significant figure.To do this we start to count significant figures starting from first non-zero digit to the actual figure we are requested to stop.We can see that 9 is after zero, the we round off that 9 then it will become 1 , Then the value to one significant figure is [tex]1.1m^{2}[/tex]Therefore, the multiplication of the values to one significant figure is [tex]1.1^{2}[/tex]

15. An electrically neutral atom consists of 15 neutrons, 13 electrons, and a number of protons. What is its mass number?
Answers
Answer:
28
Explanation:
it states that the atom is neutral, meaning the number of electrons and protons are the same. so if there are 13 electrons, there are 13 protons. And the mass number is neutrons plus protons. So 13+15 is 28
For an atom to be electrically neutral, the number of protons must be equal to the number of electrons to cancel out the charge exerted by the electrons.
Therefore, if the atom has 13 electrons, then the atom also has 13 protons. In other words, the atom has an atomic number of 13.
The mass number of an atom is the sum of the number if the atomic number or number of protons and the number of neutrons. Therefore, it’s mass number is 13+15=28.
PLEASE HELP !!! Read the passage below and use it to answer the question. Rainforests have four basic layers. The tallest trees are part of the emergent layer, which can be as much as 60 m above the ground. The sunlight is bright and hot here, and the wind can be strong. The main layer of the rainforest is the canopy, more than 20 m above the ground. It is made up of the leaves and branches of tree tops. The air here is still and very moist. The canopy blocks out most of the sunlight. Smaller trees, vines, and other plants make up the understory, which is less than 12 m above the ground. This layer is damp and warm with very little sunlight. The forest floor is dark, warm, and moist. Decomposers break up fallen leaves and other dead matter here.

Calculate the following to the correct number of significant figures 0.0041 cm x 2.00 cm
x 501 cm
Answers
Answer:
4.1 cm³
Explanation:
When multiplying, the product must have the same number of significant figures as the factor with the least number of significant figures. 0.0041 has two significant figures, 2.00 has three significant figures, and 501 has three significant figures. The answer will have 2 significant figures.
0.0041 cm × 2.00 cm × 501 cm

Which of the following is not a possible effect of increasing carbon dioxide levels in the atmosphere?a.increase in water contamination and floodsb.ocean acidificationc.cutting down forestsd.reduction of cold-related deaths Please select the best answer from the choices providedABCD
Answers
Answer:
b
Explanation:
The only option that is not an effect of increasing carbon dioxide levels in the atmosphere is cutting down forests.
An increasing level of carbon dioxide in the atmosphere causes ocean acidification due to the dissolution of the gas in the oceans. Carbon dioxide also causes global warming - an increase in the average global temperature due to the heat (from the sun) absorbing ability of the gas.
Global warming causes an increase in the level of seas and oceans as a result of the melting of glaciers and polar ice caps. The rise in sea levels causes flooding with associated loss of habitats and biodiversity.
The increase in global temperature also means that cold-related deaths will reduce.
Correct option: b

C. cutting down forests

Which statement refers to the quantum mechanical model? A) Electrons move in a circular path about the nucleus. B) Electrons can lose energy and fall into the nucleus. C) Electrons are in "orbitals", regions of space where there is high probability of being found. D) An electron can move from one circular path to another only when it absorbs or emits energy corresponding to the exact difference between the two energy states.
Answers
Answer:
Electrons are in "orbitals", regions of space where there is high probability of being found.
Explanation:
The Wave mechanical model of the atom does not restrict the electrons to certain energy levels only as in the Bohr's model, instead it describes a region around the nucleus called an orbital, where there is a high probability of finding an electron with a certain amount of energy.
Each energy level is composed of one or more orbitals and the distribution of electrons around the nucleus is determined by the number and kind of energy levels that are occupied.

How many grams of carbon (C) would be present in carbon monoxide (CO) that contains 2.666 grams of oxygen (O)?
Answers
Atomic mass of O=16
2,666x12/16=1,9995
Hope that is right
Answer:
Explanation:
Given :
Mass of oxygen containing carbon monoxide (CO) is 2.666 gram .
To Find :
How many grams of carbon (C) would be present in carbon monoxide (CO) that contains 2.666 grams of oxygen (O) .
Solution :
By law of constant composition , a given chemical compound always contains its component elements in fixed ratio (by mass) and does not depend on its source and method of preparation.
So , volume of solution does not matter .
Moles of oxygen ,
Now , molecule of CO contains 1 mole of C .
So , moles of C is also 0.167 mole .
Mass of carbon ,
Therefore , mass of carbon is 2 grams .
Hence , this is the required solution .
