Answer:

Importance of Greenhouse Gases

Greenhouse gases, such as carbon dioxide, methane, nitrous oxide, and certain synthetic chemicals, trap some of the Earth's outgoing energy, thus retaining heat in the atmosphere. This heat trapping causes changes in the radiative balance of the Earth—the balance between energy received from the sun and emitted from Earth—that alter climate and weather patterns at global and regional scales.

Multiple lines of evidence confirm that human activities are the primary cause of the global warming of the past 50 years.1 Natural factors, such as variations in the sun's output, volcanic activity, the Earth's orbit, the carbon cycle, and others, also affect Earth's radiative balance. However, beginning in the late 1700s, the net global effect of human activities has been a continual increase in greenhouse gas concentrations.

What is 17/9 as a whole number
Julli [10]
Haha, I used to do IXL all the time. Continuing onto the question, it's asking it in mixed number form..

17/9, how many 9's go into 17? I'd say 1 time, or if we 2 we'd go over.

so 1 times 9 = 9

What's the remainder? 17-9=8

so you've got only one whole 9, and 8 left over

so {{ 1 8/9 }} is the answer

I WILL MARK BRAINLIEST IF YOU ANSWER
natka813 [3]

Answer:

A. The Democrats have controlled the House of Representatives majority of the years since 1900. There have been about 35/60 times in the chart where the Democrats have controlled the House of Representatives. The Democrats have also controlled the Senate for the most since 1900. The Senate has been controlled by Democrats around 34/60 according to the chart. There have been 31 Republican presidents, and 28 democratic presidents since the 1900s. The Republicans have controlled the majority of the presidency.

B. The presidency and congress have more often than not been controlled by different parties. This can make passing laws more difficult and can result in many vetoes, and filibusters. Though it does not make it impossible because of the separation of powers.

C. The separation of powers allows for congress to pass bills even if the president vetoes them. The separation of powers allows for the roles of each branch to stay the same. It also allows for each branch to do their job even if they aren’t affiliated with the same party.

Suppose you have 61.8 grams of elemental chromium. How many grams would be the isotope chromium - 50?
lilavasa [31]

Answer:

The mass of the isotope Chromium-50 would be 2.685 grams in 61.8 grams of elemental Chromium.

Explanation:

Natural chromium (Cr) is composed of four stable isotopes: ^{50} Cr (4.345 % abundance), ^{52}Cr (83.789 % abundance), ^{53}Cr (9.501 % abundance) and ^{54}Cr (2.365 % abundance). We can obtained the total mass of the isotope Chromium-50 (m_{^{50}Cr}), measured in grams, by multiplying the mass of elemental chromium (m_{Cr}), measured in grams by percentage ratio (r), dimensionless. That is:

m_{^{50}Cr} = \frac{r}{100}\cdot m_{Cr}

If we know that r = 4.345 and m_{Cr} = 61.8\,g, then the mass of isotope Chromium-50 would be:

m_{^{50}Cr} = \frac{4.345}{100}\cdot (61.8\,g)

m_{^{50}Cr} = 2.685\,g

The mass of the isotope Chromium-50 would be 2.685 grams in 61.8 grams of elemental Chromium.
