Answer:

The invasive species would take over in the area and throw off the balance of the ecosystem.

Explanation:

Invasive species can harm both the natural resources in an ecosystem as well as threaten human use of these resources. An invasive species can be introduced to a new area via the ballast water of oceangoing ships, intentional and accidental releases of aquaculture species, aquarium specimens or bait, and other means.

Invasive species are capable of causing extinctions of native plants and animals, reducing biodiversity, competing with native organisms for limited resources, and altering habitats. This can result in huge economic impacts and fundamental disruptions of coastal and Great Lakes ecosystems.

Which of the following steps can be used to identify a single replacement reaction? (5
points)
O Check whether the products are salt and water.
O Check if the ions of two compounds exchange places.
o Check if one element replaces another element in a compound.
Check whether the reactants are an acid and a base.

Answers

Answer:

d

Explanation:

check if one element replaces another element in a compound

The single replacement reaction can be identified when there has been the replacement of one element with another element in the compound. Thus, option C is correct.

The replacement reaction can be defined as the reaction in which the highly reactive element replaced the low reactive element in the reaction and forms a compound.

The reaction has been given as:

X + AY [tex]\rightarrow[/tex] AX + Y

The X has been highly reactive than Y replaces Y in the compound and forms the compound AX.

The single replacement reaction can be identified when there has been the replacement of one element with another element in the compound. Thus, option C is correct.

Which type of bond will chromium atoms likely to form with other chromium atoms
A:ionic
B:covalent
C:metallic

Answers

Answer: B

Explanation: Covalent bonds where electrons are not shared equally between two atoms are called polar covalent bond. As shown above, the electrons in a covalent bond between two different atoms (H and Cl in this case) are not equally shared by the atoms. This is due to the electronegativity difference between the two atoms.

There are two types of chemical compound one is covalent compound and other is ionic compound in chemistry. The covalent bond will be formed between two chromium atoms. the correct option is option B.

What is chemical Compound?

Chemical Compound is a combination of molecule, Molecule forms by combination of element and element forms by combination of atoms in fixed proportion.

Covalent bond formed by sharing of electron and ionic bond formed by complete transfer of electron.

Element with same electronegativity difference combine together by covalent bond whereas ionic bond is formed by elements whose electronegativity difference is high.

As two chromium is combining that is two two element with same electronegativity is combining therefore, formation of covalent bond is the only possibility.

Therefore covalent bond will be formed between two chromium atoms. the correct option is option B.

A 200.0-mL sample of helium gas is in a cylinder with a movable piston at 110 kPa and 275 K. The piston is pushed in until the sample has a volume of 95.0 mL. The new temperature of the gas is 310. K. What is the new pressure of the sample?

51.1 kPa
261 kPa
249 kPa
274 kPa

Answers

Answer:

P₂ = 261 KPa

Explanation:

Given data:

Volume of sample = 200 mL

Initial pressure = 110 KPa

Initial temperature = 275 K

Final volume = 95 mL

Final temperature = 310 K

Final pressure = ?

Solution:

Formula:

P₁V₁/T₁ = P₂V₂/T₂

P₂ = P₁V₁T₂ /T₁ V₂

P₂ = 110 KPa× 200 mL× 310 K /275 K  × 95 mL

P₂ = 6820000 KPa / 26125

P₂ = 261 KPa

If the atomic number increases then the atomic radius should decrease right? So what’s wrong with my data

Answers

Answer:

Atomic radius increases by increasing the atomic number.

Explanation:

Atomic radius :

Atomic radius is the distance between nucleus of an atom to its outer most electronic shell.

Trend along group:

As we move down the group atomic radii increased with increase of atomic number. The addition of electron in next level cause the atomic radii to increased. The hold of nucleus on valance shell become weaker because of shielding of electrons thus size of atom increased.

As the size of atom increases the ionization energy from top to bottom also  decreases because it becomes easier to remove the electron because of less nuclear attraction and as more electrons are added the outer electrons becomes more shielded and away from nucleus.

The given data show that the atomic number in increased from 4 to 88 it means atomic radius also increased from 1.53Å to 2.83Å. It means the given data is the elements of periodic table present in group. It is the data of 2nd group of periodic table.

Arrange the following in order of increasing atomic radius: Mg, Na, P, Si, and Ar.

Answers

Answer:

Ar, P, Si, Mg, Na

Explanation:

Ar=106pm

P=107pm

Si=111pm

Mg=141pm

Na=166pm

Na>Mg>Si>P>Ar is the order of increasing atomic radius.

What are elements?

Elements are the simplest substances which cannot be broken down using chemical methods.

Atomic radii vary in a predictable way along or across the periodic table. The atomic radius increases from top to bottom in a group, and decreases from left to right across a period. Thus we can say that helium is the smallest element, and francium is the largest.

Ar=106pm

P=107pm

Si=111pm

Mg=141pm

Na=166pm

Hence, Na>Mg>Si>P>Ar is the order of increasing atomic radius.

Bobbye wants to know how his speed affect the amount of time it takes to stop at a stop sign. Each time he performs a trial, he will change the speed that he is driving to see how it affects the amount of time it takes to stop. ​ Independent Variable:​ ​ ​ Dependent Variable:​ ​ ​ Controlled Variables:​

Answers

Answer:

The correct answer is -

Independent Variable:​ change of speed​ ​

Dependent Variable:​ time takes to stop​ ​

Controlled Variables:​ stop at a stop sign

Explanation:

To know the effect of the speed to take the time to stop at a stop sign Bobbye perform this exercise where he changes the speed at each time that he is driving to know the time it takes to stop at a stop sign. There is a change that takes place purposely is in the speed of driving so it is an independent variable as the independent variable is a variable that is manipulated in an experiment or investigation.

The time it takes to stop is the factor that depends on the speed so it is the dependent variable as the dependent variable is the variable that depends on the independent variable.

The control variable remains the same or constant in an investigation which is stoping at a stop time irrespective of speed.
