3 characteristics of the carbon atom that makes possible the building of variety of biological molecules are:
• Carbon atoms can easily form covalent bonds with nitrogen, hydrogen, oxygen, sulfur and with carbon. The bonds can be single, double or triple between the atoms. This combination of carbon with other elements and with itself results in the formation of huge number of biological molecules.
• The size of carbon atom is very small in comparison to most other atoms. Thus, the bond formed between two carbon atoms is quite short. And the shorter bonds are more stronger than the longer bonds between two atoms, that's why carbon bonds are stable at the different temperatures associated with life.
• Only carbon can form stable four covalent bonds with the other elements, which makes it versatile element to serve as the basic structural component, of the macro-molecules.
Answer:
B
Explanation:
first we apply electricity and by the help of circuits it will get toasted which means it will get heated so the answer is B
Answer:
hi
Explanation:
A mixture which has uniform composition throughout its mass is called homogeneous mixture. The word "homo" means "same". For example, when you completely dissolve salt in the water, you form a homogeneous mixture.
1. P = F/A; weight is a force (the force of gravity on an object), so divide the weight by the area given. P = 768 pounds/75.0 in² = 10.2 pounds/in².
2. Using the same equation from question 1, rearrange it to solve for A: A = F/P. We're given the force (the weight) and the pressure, so A = 125 pounds/3.25 pounds/in² = 38.5 in².
3. Again, using the same equation from question 1, rearrange it this time to solve for F: F = PA = (4.33 pounds/in²)(35.6 in²) = 154 pounds.
4. We can set up a proportion given that 14.7 PSI = 101 KPa. This ratio should hold for 23.6 PSI. In other words, 14.7/101 = 23.6/x; to solve for x, which would be your answer, we compute 23.6 PSI × 101 kPa ÷ 14.7 PSI = 162 kPa.
5. We are told that 1.00 atm = 760. mmHg, and we want to know how many atm are equal to 854 mmHg. As we did with question 4, we set up a proportion: 1/760. = x/854, and solve for x. 854 mmHg × 1.00 atm ÷ 760. mmHg = 1.12 atm.
6. The total pressure of the three gases in this container is just the sum of the partial pressures of each individual gas. Since our answer must be given in PSI, we should convert all our partial pressures that are not given in PSI into PSI for the sake of convenience. Fortunately, we only need to do that for one of the gases: oxygen, whose partial pressure is given as 324 mmHg. Given that 14.7 PSI = 760. mmHg, we can set up a proportion to find the partial pressure of oxygen gas in PSI: 14.7/760. = x/324; solving for x gives us 6.27 PSI oxygen. Now, we add up the partial pressures of all the gases: 11.2 PSI nitrogen + 6.27 PSI oxygen + 4.27 PSI carbon dioxide = 21.7 PSI, which is our total pressure.
Hey there!
The correct answer to your question is: Spectrum
A spectrum, by definition, is a range of colors which are produced by separating certain colors of light.
Thank you!
