In this exercise we have to use our knowledge of acid rain, as:
Only methane fires will not produce acid rain since acid rain usually occurs in areas of high population concentration, industries and with high levels of emission of pollutants such as CO2 and methane.
The main consequences of acid rain are: The soil can change when acid rain reaches the surface, becoming acidified. Soil contamination can also cause contamination of water courses, such as rivers and lakes, as well as underground water reserves.

there is no choices but A binary compound is a compound composed of only two elements. Binary compounds composed of a metal and a non metal and are named as ionic compounds.
Lithium fluoride LiF
Lithium chloride LiCl
Lithium phosphide Li3P
Beryllium fluoride BeF2
Beryllium chloride BeCl2
Beryllium bromide BeBr2
Beryllium iodide BeI2
Beryllium phosphide Be3P2
Boron fluoride BF3
Boron chloride BCl3
hope this helped :) pls give branliest
A binary ionic compound is composed of ions of two different elements - one of which is a metal, and the other a nonmetal.
B. Density
C. Melting point
D. Color
Answer : The properties which would be the same among isotopes of the same element are Flammability and Color
Explanation :
Isotopes are the elements that have same number of electrons and protons but they differ in number of neutrons.
The chemical properties of an element are determined by its valence electrons and since isotope have same number of electrons, they have similar chemical properties.
But isotopes have different number of neutrons. Neutrons are the subatomic particles which are present in the nucleus. They are charge less particles and they have mass. Therefore when the elements have different number of neutrons, their atomic masses differ.
As a result, isotopes have different mass related physical properties.
Let us discuss the given properties now
1) Flammability : Flammability in simple words means the ability of the substance to catch fire or the ability to burn. This is mainly dependent on the reactivity which is in turn dependent on the number of electrons.
Since the isotopes have same number of electrons, they show similar flammability.
2) Density : Density is defined as mass per unit volume. This property involves mass and we know that isotopes have different masses. Therefore they have different densities too.
3) Melting point : Melting point is a physical property which is mainly dependent on the molecular weight of the substance. Since isotopes have different masses, they tend to show different melting points.
4) Color : The color of the element is mainly dependent on the arrangement of electrons around the nucleus. Isotopes have same number of electrons which means the arrangement would also be the same. Therefore the isotopes of the same element do not show different colors.
The properties which would be same among isotopes of the same element are
1) Flammability
4) Color
Answer: D. Color
Explanation: Founders Educere answer.
So much for expert verified^^ smh
Explanation:
solution is neutral because it added water and water is neutral solution
1.986 x 10negative exponent 6 or 1.986 x 10^6
Answer:
Explanation:
We have the number . Standard notation would basically be this number without the part.
To get rid of this part, we need to move the decimal point 6 places to the left (we go left because it's negative 6, indicating division).
So, when we move the decimal point 6 places to the left, the resulting number is: , with 5 zeros after the decimal point before a nonzero number.
Thus, the answer is .
Answer: Conduction
Explanation: MODES OF HEAT TRANSFER
Conduction: This type of heat transfer happens when there is direct contact between the two object.
Convection: This type of heat transfer happens when there is a movement of fluid (liquid or gas).
Radiation: This type of heat transfer happens when there is direct transfer of energy through space.
Thus as there is direct contact between the mug and the tea, the heat transfer occurs through conduction.
What is the pressure, in atm, of the methane gas?
Express the answer using 3 significant figures.
atm
Answer:
P = 0.979 atm
Explanation:
Given data:
Number of moles of methane = 40.8 mol
Volume of container = 1020 L
Temperature = 298 K
Pressure of gas =?
Solution:
According to ideal gas equation,
PV = nRT
P = pressure
V = volume
n = number of moles
R = general gas constant
T = temperature
Now we will put the values,
P = nRT/V
P = 40.8 mol × 0.0821 atm.L/mol.K × 298 K / 1020 L
P = 998.2 atm /1020
P = 0.979 atm
