The electronegativities of the two atoms play a part in determining what kind of bonds are formed. The main two types of chemical bonds are ionic and covalent. Covalent bonds are formed by atoms that share valence electrons and are most commonly formed between nonmetal atoms.
Their valance electrons are redistributed in ways that make the atoms more stable.
Answer:
nitrogen fixation
Explanation:
nitrogen fixation is the process through which the nitrogen fixing rhizobium bacteria present in the root nodules of leguminous plants I fixes the nitrogen present in the air into the soil
Answer:
tar and nicotine which are produced when the tobacco leaves are burning.
Answer:
1419.21 mL
Explanation:
From the question;
We are required to determine the volume of the oil in mL
Volume = Mass ÷ Density
= 1.3 kg ÷ 0.916 kg/L
= 1.41921 L
BuT, 1 l = 1000 mL
Therefore;
Volume = 1.41921 L × 1000 mL/L
= 1419.21 mL
Hence, the volume of olive oil is 1419.21 L
To find the volume of the oil, we can use the formula density = mass/volume. The density of olive oil is approximately 0.92 g/mL. Converting the mass of the oil from kilograms to grams, we find that the volume of the oil is approximately 1413.04 mL.
To find the volume of the oil, we need to convert the mass of the oil to volume using its density. The density of olive oil is approximately 0.92 g/mL. First, we need to convert the mass of the oil to grams:
1.3 kg * 1000 g/kg = 1300 g
Next, we can use the formula density = mass/volume to find the volume:
0.92 g/mL = 1300 g/volume
Solving for volume gives us:
volume = 1300 g / 0.92 g/mL = 1413.04 mL
Therefore, the volume of the oil is approximately 1413.04 mL.
#SPJ3
B) The element is most likely from Group 2A or 3A and in period 2 or 3.
C) The element is most likely from Group 4A or 5A and in period 4 or 5.
D) The element is most likely from Group 6A or 7A and in period 6 or 7
Answer:
The list of answer choices is wrong.
The correct list is:
A) The element is most likely from Group 1A or 2A and in period 1 or 2.
B) The element is most likely from Group 2A or 3A and in period 6 or 7.
C) The element is most likely from Group 4A or 5A and in period 4 or 5.
D) The element is most likely from Group 6A or 7A and in period 2 or 3.
The correct answer is:
Explanation:
The ionization energy increases from left to right on the periodic table. So the elements with higer ionization energies are in the right end of the table. The right most columns are 6A (16) and 7A(17). The column 8A (18) which is that of the noble gases is not normally taken into acccount for this predictions because noble gases are nearly inert.
Hence, the fact that the statement indicates high ionization energy suggests that the element is most likely from group 6A or 7A.
The atomic radius increases from top to bottom, so the smallest elements are in the top rows, which is the periods 1, 2, or 3. The period 1 only has two elements, hydrogen in group 1 and helium in group 8A, so they are not considered in the choices. Thus, that leaves you with the periods 2 or 3.
Adding the two considerations, the conclusion is that the element is most likely from group 6A or 7A and in period 2 or 3.
Answer:
Explanation:
The answer is A) The element is most likely from Group 1A or 2A and in period 1 or 2
