You did not write any of those chemical names correctly (methane is CH4, not ch4) and all you did was list 4 incorrectly written chemicals, you did not give a chemical equation. Only a chemical reaction can be described as endothermic or exothermic; chemicals by themselves do not have those properties.

Is decomposition of limestone endothermic or exothermic?
endothermic
Are humans endothermic?
Yes. A human is endothermic, able to maintain its own body temperature. It is a mammal, and mammals and birds are endothermic. The term 'endothermic' is the biological term for an animal that is warm-blooded.
Are dogs endothermic?
Yes dogs are endothermic. Their body heat is controlled by their metabolic rate just like humans and other mammals. Some dogs have a hard time cooling down, like boxers, and heating up, like Chinese Cresents, but they are endothermic.
What is a endothermic?
An endothermic reaction is a chemical reaction that absorbs heat from its surroundings. change in H> 0.(6.6)
How many moles in 64 grams of CH4?
There are 0.75 moles in it.You have to devide 12 by molecular mass
What is the balance chemical equation for production of carbon tetrachloride?
The reaction is: CH4 + 4Cl2---------------------CCl4 + 4HCl
What type of reaction is 2N2O5 plus NO 4NO?
CH4 + 2O2 📷 CO2 + 2H2O + Heat
What is this reaction co2 2h2o ch4 2o2 h 802 kj?
The reaction you provided is the chemical equation for the combustion of methane (CH4) in the presence of oxygen (O2) to produce carbon dioxide (CO2), water (H2O) and release energy in the form of heat (802 kJ).
How do you combine carbon and chlorine?
CH4 + 4Cl2 -----> CCl2 + 4HCl This is the current common method of tetrachloride synthesis, under heat and pressure, although another involves further chlorinating of chlorocarbons e.g. C2Cl6 + Cl2. Earlier methods used chloroform or disulphide, reacted with chlorine.
Balanced chemical equation of hydrochloric acid and oxygen?
The balanced chemical equation for the reaction between hydrochloric acid (HCl) and oxygen (O2) is: 4HCl + O2 -> 2H2O + 2Cl2
What is the name of the substance oxidized in 2cl2 plus 2h2o and 4hcl plus o2?
oxygen
How many moles of CH4 are in 200 grams of CH4?
200 g CH4 x 1 mole CH4/16 g = 12.5 moles CH4
What is the chemical formule for methane gas?
The chemical formula for methane gas is CH4. It is composed of one carbon atom bonded to four hydrogen atoms.
Why is CH4 polar?
CH4 is a nonpolar molecule because the carbon atom is in the center with four identical hydrogen atoms surrounding it in a symmetric tetrahedral arrangement. This results in a symmetrical distribution of charge and no significant dipole moment, making CH4 nonpolar.
What will take place if titanium dioxide is reacted with hydrochloric acid?
When titanium dioxide is reacted with hydrochloric acid, titanium chloride and water are formed. This reaction typically produces a white precipitate of titanium chloride, while the excess hydrochloric acid remains in the solution.
Is distilling petroleum Exothermic and endothermic?
The process of distilling petroleum is endothermic because it requires heat energy to break down the hydrocarbon compounds in the crude oil into lighter fractions. This heat energy is needed to vaporize the oil so it can be separated by boiling point.
Are mollusks endothermic or ectothermic?
endothermic
