_____ magma is a mix between basaltic and rhyolitic magma. The eruption that would most likely result from this magma is a _____ eruption.

Answers

Answer 1
Answer:

Answer:

Explanation:

_Andesitic__ magma is a mix between basaltic and rhyolitic magma. The eruption that would most likely result from this magma is a _strombolian____ eruption.

Andesitic magma straddles between basaltic and rhyolitic magma. They produce rocks that shows both basaltic and rhyolitic affinity. Examples of rocks that results from this type of magma is andesite.

Strombolian eruptions results from this type of magma. They are charactised by moderate to low bursts of magma. Their explosivity is between 2 and 3.

Pedro is baking a cake for his experiment on chemical changes. He knows a chemical change will occur when he puts the cake mixture in the oven. He would like to know what will happen when the cake is removed from the oven. What prediction would you make for Pedro's experiment? A. The chemical changes occurred because the chemicals changed. B. The chemical changes occurred because there was a change in light energy. C. The fruit and the hamburgers were affected by an increase in heat energy. D.The fruit and the hamburgers were affected by a decrease in heat energy.

Answers

Answer:

A. The chemical changes occurred because the chemicals changed.

Explanation:

When baking a cake several chemical reactions occur that change the chemical composition of the ingredients used in baking. An ingredient like baking powder releases carbon dioxide when it undergoes a temperature change in the oven. A chemical change is supposed to change the form of a substance.

An endothermic reaction also occurs when the ingredients absorb heat energy to produce several changes. The firmness of the cake occurs because of the heat absorbed by the proteinous content of the egg.

A buffering solution consists of both strong acids and bases.
a. True
b. False

Answers

False. A buffering solution consists of a WEAK acid such as CH3COOH, C5H5N, or ammonia. A buffering solution resists pH change upon the addition of an acidic or basic components. It can neutralize little amounts of added acid or base, thus maintaining the pH of the solution relatively stable. The correct answer is letter "B. false"
