Two different metals, each with a mass of 50.0g, are placed so they directly touch each other. Metal A has a higher initial temperature than Metal B. You calculate the value of q (the heat content) of Metal A correctly as 300 calories. Which statement is true about the heat flow between metal A and Metal B, assuming there is no other heat loss? • Metal A will gain 300 calories and Metal B will lose 300 calories
• Metal A will lose 300 calories and Metal B will gain 300 calories
• Metal A will gain 200 calories and Metal B will lose 100 calories
• Metal A will lose 200 calories and Metal B will gain 100 calories

Consider the following unbalanced equation for the combustion of hexane: αc6h14(g)+βo2(g)→γco2(g)+δh2o(g) part a balance the equation. give your answer as an ordered set of numbers α, β, γ, use the least possible integers for the coefficients. α α , β, γ, δ = nothing request answer part b determine how many moles of o2 are required to react completely with 5.6 moles c6h14. express your answer using two significant figures. n n = nothing mol request answer provide feedback

What two categories of toxins were present in the air at dish, texas as a result of the gas pipelines that pass through the area

Astudent made the lewis dot diagram of a compound as shown. mg is written with two dots shown on its top. an o is written on each side of mg. each o has six dots around it. an arrow is shown from one dot on mg toward the vacant space around the o on the right. another arrow is shown from the other dot on mg toward the vacant space around the o on the left. the title of the art is students lewis dot model. what is the error in the lewis dot diagram? an o atom should transfer all its six electrons to mg because the formula is mgo. both electrons of mg should be transferred to one o atom because the formula is mgo. the electrons should be transferred from each o atom to mg because mg has fewer electrons. the number of dots around mg should be four because it has to transfer two electrons to each o.
