<span>A combustion reaction is when a substance reacts with oxygen and releases energy in the form of light and heat. A combustion reaction will always includes a hydrocarbon and oxygen as the reactants and always produces carbon dioxide and water as products. Therefore your answer of A is correct.</span>
Answer:
The concentration of the acid is 117.92 ± 0.03 mM.
Explanation:
In this problem, the concentration of NaOH and the volume used is given. The volume pipetted from the acid is also given. The concentration of the acid is given by:
CNaOH * VNaOH = Cacid * Vacid
158.32 * (18.76-0.14) = C acid * 25
C acid = 117.92 mM
The propagation of error for this problem, which is a multiplication is the concentration of the acid multiplied by the error divided by its respective value as shown in the equation below
error = 117.92 * 
The answer is 0.03 mM of uncertainty.
Answer:
Wind erosion abrades surfaces and makes desert pavement, ventifacts, and desert varnish. Sand dunes are common wind deposits that come in different shapes, depending on winds and sand availability.
Vanadium(V) oxide is the inorganic compound with the formula V₂O₅. Commonly known as vanadium pentoxide, it is a brown/yellow solid, although when freshly precipitated from aqueous solution, its colour is deep orange. Because of its high oxidation state, it is both an amphoteric oxide and an oxidizing agent.
formula:V2O5

The answer is A because latent heat is the heat released or absorbed by a body or a thermodynamic system during a constant temperature process.
an example is like melting ice or boiling water. these are example's but like i said the answer is A.
