Answer:

c. 80 g

Explanation:

metal alloy:

  • wt% = (mass compound/mass alloy)×100

for antimony:

⇒ 16% = (g antimony / g alloy)×100

⇒ 0.16 = g antimony / g alloy

∴ g alloy = 500 g

⇒ (0.16)×(500 g) = g antimony

⇒ g antimony = 80 g

Can the ratio of hydrogen to oxygen change if a solute is dissolved in the water
coldgirl [10]

Answer:

Water molecules feature the combinations of hydrogen and oxygen atoms in a 2:1 ratio. Since they are present in a fixed ratio of mass, water molecules obey the law of constant proportions. Water is formed when two molecules of the diatomic hydrogen gas, combine with one molecule of the diatomic oxygen gas to produce two molecules of water

Many towns in flood-prone areas are surrounded by___ that are built to hold back rising water.
xxTIMURxx [149]

Answer:

Flood barriers

Explanation:

Many towns in flood-prone areas are surrounded by flood barriers that are built to hold back rising water during seasonal highs.

  • Flood barriers are water resistant walls that are used to prevent breaking water during a high period of inundation from their channels.
  • They are usually vertical artificial structures which can be temporary or permanent.
  • They help to hold or contain the flood water during the high season.
  • These walls prevents flood plains and other nearby areas from getting flooded during the rainy season.

If another hydrogen of c2h5cl is replaced by a chlorine atom to yield c2h4cl2, how many isomers would result?
Mandarinka [93]

One isomer is formed

1,1- Dichloroethane is the isomer.

If another hydrogen of c2h5cl is replaced by a chlorine atom to yield c2h4cl2, it would result in one isomer.

  • In contrast to 1,2-dichloroethane, which has two chlorine atoms connected to distinct carbon atoms, 1,1-dichloroethane has two chlorine atoms bound to the same carbon atom.
  • Isomers are each of two or more compounds having the same formula but various atom arrangements in the molecule and unique characteristics.

<h3>What three types of isomers are there?</h3>
  • Chain isomers
  • Functional group isomers
  • Positional isomers

These are the three different categories of structural isomers.

<h3>How is an isomer recognized?</h3>
  • Their bonding patterns and the way they occupy three-dimensional space can be used to distinguish them.
  • Determine the bonding patterns of structural (constitutional) isomers.
  • Although the atoms in the compounds are the same, their connections create various functional groups.

<h3>What makes isomers significant?</h3>
  • Because two isomers might have the same chemical formula but different chemical structures, they are significant.
  • The molecule's properties are influenced by its structure.

What did J. J. Thomson observe when he applied electric voltage to a cathode ray tube in his famous experiment?
Nataly_w [17]

The glass opposite to the negative electrode started to glow. Hence, option B is correct.

<h3>What is a cathode ray tube?</h3>

A cathode-ray tube (CRT) is a specialized vacuum tube in which images are produced when an electron beam strikes a phosphorescent surface.

J.J. Thomson, through his famous Cathode ray experiment, proved that all atoms contain small negatively charged particles known as electrons. In the experiment, he applied electric voltage across a cathode ray tube. a fluorescent material coating was done on the positive side. When the voltage was applied, the positive side has glowing dots.

Hence, option B is correct.
