box a and box b have the same density. box a had more volume. which box has more mass?
Answer:
Box A.
Explanation:
Density can be defined as mass all over the volume of an object.
Simply stated, density is mass per unit volume of an object.
Mathematically, density is given by the equation;
[tex]Density = \frac{mass}{volume}[/tex]
In this scenario, Box A and Box B have the same density. However, Box A had more volume. Therefore, the box that would have more mass would be Box A because it has more capacity or volume to hold more matter.
This ultimately implies that, the volume of a box is directly proportional to its mass (amount of matter it can hold); the higher the volume of the box, the higher its mass (more mass).
Let's assume Box A has a volume of 25cm³ and a mass of 50kg.It's density would be;
[tex]Density = \frac{50}{25}[/tex]
Density = 2kg/cm³
Assuming Box B has a volume of 10cm³ and a mass of 20kg.It's density would be;
[tex]Density = \frac{20}{10}[/tex]
Density = 2kg/cm³
Therefore, it can be deduced that even though Box A and Box B have the same density; Box A had more volume and consequently, more mass.

zinc metal reacts with hydrochloric acid to produce hydrogen gas.
what best describes this reaction?
a. A single replacement reaction takes place because zinc is more reactive and hydrogen
b. A single replacement reaction takes place because zinc is more reactive than chlorine
c. A double replacement reaction takes place because zinc is less reactive than hydrogen
d. A double replacement reaction takes place because zinc is less reactive than chlorine
a. A single replacement reaction takes place because zinc is more reactive and hydrogen
Further explanationIn voltaic series
Li-K-Ba-Ca-Na-Mg-Al-Mn- (H2O) -Zn-Cr-Fe-Cd-Co-Ni-Sn-Pb- (H) -Cu-Hg-Ag-Pt-Au
The more to the left, the metal is more reactive (easily release electrons) and the stronger reducing agent
The more to the right, the metal is less reactive (harder to release electrons) and the stronger oxidizing agent
So that the element located on the left can push the element on the right in the redox reaction
Reaction
Zn+2HCl ⇒ ZnCl₂ + H₂
If we look at this reaction, the elements that play a role are those that undergo a redox reaction
Oxidation : Zn⇒Zn²⁺ + 2e
Reduction : 2H⁺ + 2e ⇒H₂
So Zn (located on the left) can push H (the element on the right) in the redox reaction ⇒ Zn more reactive
A single replacement reaction is a chemical reaction in which one element replaces the other elements of a compound to produce new elements and compounds
A+BC⇒AC+B
So the above reaction involves the elements Zn and H which undergo a redox reaction and are included in a single replacement

Which will most likely happen to her soup?
Carlotta adds too much salt to her soup. She recalls that
evaporation can be used to separate salt from salt water,
so she plans to leave the soup on the stove on low heat
until the soup is less salty.
O The soup will become saltier because evaporation
removes the water and leaves the salt behind.
O The procedure will make the soup less salty because
the salt will evaporate and leave the pot.
The saltiness of the soup will not change because
both salt and water will evaporate.
O The heat will cause the soup to become more salty
because more salt dissolves in hotter water.
Answer: A! The soup will become saltier because evaporation removes the water and leaves the salt behind.

A piece of gold has a mass of 21.7 kg and a volume of 5.78 cm3 . What is the density of gold? (Convert kgg)
Answer:
The answer is 3754.33 g/cm³Explanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\ [/tex]
From the question
mass = 21.7 kg = 21700 g
volume = 5.78 cm³
We have
[tex]density = \frac{21700}{5.78} \\ = 3754.3252...[/tex]
We have the final answer as
3754.33 g/cm³Hope this helps you

How do geologists know that there once was a vast sea where the Grand Canyon is today?
The geologists know the presence of the vast sea at Grand Canyon by the erosion and indentations.
Grand Canyon in Arizona has been the rock sediment. It has been determined to be the vast sea due to the presence of oceanic floors. The erosion of the rocks results in the formation of the land over a vast period of time.
The rock indentation results in the formation of the mountains. The rock has been indented with the force thus, there has been the oceanic force that results in the indentations.
Thus, the erosion and indentations have resulted in the formation of the Grand Canyon by a vast sea.
