In weather report generally the temperature conditions and the extent of humidity is described. Humidity is nothing but presence of water in its vapour form. Hence the only gas which is being reported in a weather report must be water vapour. The other gases like oxygen carbon dioxide or noble gases or nitrogen are never mentioned in a normal weather report issued in public interest

A.polar water, nonpolar oil
B.polar vinegar, nonpolar nail polish
C. polar bleach, polar water
D.nonpolar mineral oil, polar alcohol
Answer:
C
Explanation:
polar has unequal sharing of electrons that has the lone pairs which has the electronegativity difference. can be mixed with water.
The combination of polar bleach and polar water would likely be most miscible with each other as substances with similar molecular structures and polarities tend to mix. This is based on the rule of 'like dissolves like' in chemistry.
The question is asking which combination of substances would be most likely to mix, or be miscible, in one another. Miscibility is a property in chemistry relating to whether different substances can combine into a homogeneous mixture without separating.
The rule of thumb in chemistry is 'like dissolves like' which means that substances with similar molecular structures and polarities tend to be miscible with each other. Therefore, among the provided options, the combination of polar bleach and polar water (Option C) would be the most likely to mix with each other as they are both polar substances.

Answer:
1. micro
2. centi
3. milli
4. kilo
Explanation:
Prefixes, in mathematical exponents, are defined as the alphabetical names associated with the mathematical factors. Some examples are as follows:
10⁶ = Mega
10⁹ = Giga
10⁻⁹ = Nano
10⁻¹² = Pico
So, in order to name the metric system prefixes associated with each of the given mathematical factor, we first convert the factor into exponent form and then write its prefix, as follows:
10⁻⁶ = micro
1/100 = 0.01 = 1 x 10⁻² = centi
0.001 = 1 x 10⁻³ = milli
1000 = 1 x 10³ = kilo
B) 3
C) 4
D) 7
Answer
A(1)
Explanation:
If you don't see a coefficient, which is the big number in front of the formula, then it's only one molecule.
Example of coefficient
4H3PO4
Answer:
1,080 m
Explanation:
Keg=4.0 x 10-10
What is the value of Key for 2CO2(g) + 2COR + O2g) ?
Answer:
Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to calculate the equilibrium constant value for the reverse reaction:
By knowing that the equilibrium expression is actually:
Thus, we plug in and solve for the inverse of Keq to obtain Key as follows:
