Which of the following events must occur at point 6 in order to transform sedimentary rock into igneous rock?
A
Shifting tectonic plates push the sedimentary rock toward the poles, where it freezes and hardens into igneous rock.
B
Extreme winds and storms weather the sedimentary rock into particles, which collect in rivers and are compacted into igneous rock.
C
Rising oceans erode mountains of sedimentary rock into particles, which sink and get compacted into layers that form igneous rock.
D
Tectonic plates push against each other, driving sedimentary rock under Earth's surface, where it melts into magma and turns into igneous rock as it cools
Answer:
I belive the answer is D

Complete and balance each of the following equations for gas evolution reactions HCl(aq)+ZnS(s)>
2HCl(aq) + ZnS(s) ⇒ ZnCl₂(aq) + H₂S(g)
Further explanationEqualization of chemical reactions can be done using variables. Steps in equalizing the reaction equation:
1. gives a coefficient on substances involved in the equation of reaction such as a, b, or c, etc. 2. make an equation based on the similarity of the number of atoms where the number of atoms = coefficient × index (subscript) between reactant and product 3. Select the coefficient of the substance with the most complex chemical formula equal to 1Reaction
HCl(aq) + ZnS(s) ⇒ ZnCl₂(aq) + H₂S(g)
1. give equation
aHCl(aq) + bZnS(s) ⇒ ZnCl₂(aq) + cH₂S(g)
2. make an equation
H, left=a, right=2c⇒a=2c(eq 1)
Cl, left=a, right=2⇒a=2⇒c=1(from eq 1)
Zn, left=b, right=1⇒b=1
So the equation :
2HCl(aq) + ZnS(s) ⇒ ZnCl₂(aq) + H₂S(g)

Rahul was given iron filings and sulphur powder. He prepared a compound of iron sulphide by heating the components in a china dish. What would be his observation if he adds a few drops of dilute sulphuric acid into the compound?
Answer:
A gas with a rotten egg smell is evolved
Explanation:
When iron fillings and sulphur were heated in the vessel, the following chemical reaction took place;
Fe(s) + S(s) -----> FeS(s)
This is a direct combination reaction.
Subsequently, when dilute H2SO4 is added, the following reaction takes place;
FeS(s) + H2SO4(aq) ------> FeSO4(aq) + H2S(g)
He immediately observes the evolution of a gas with a rotten egg smell.
How does solubility impact the temperature?
Answer:
For many solids dissolved in liquid water, the solubility increases with temperature. The increase in kinetic energy that comes with higher temperatures allows the solvent molecules to more effectively break apart the solute molecules that are held together by intermolecular attractions.

Which of the following is an oxidation-reduction reaction? ZnS(s) + 2O2(g) ZnSO4(s) CaO(s) + H2O(l) Ca(OH)2(s) 6Li2O(s) + P4O10(g) 4Li3PO4(s) SO2(g) + H2O(l) H2SO3(aq)
ZnS(s) + 2O₂(g) ⇒ZnSO₄(s)
Further explanationThe oxidation-reduction reaction or abbreviated as Redox is a chemical reaction in which there is a change in oxidation number
Oxidation is an increase in oxidation number, while reduction is a decrease in oxidation number.
Reaction
ZnS(s) + 2O₂(g) ⇒ZnSO₄(s)
S²⁻ (-2 in ZnS) to S⁺⁶(+6 in ZnSO₄) ⇒ oxidation

d=distance=m
t=time,s
convert from km/h to cm/s :

During the lab, the teacher mislabels one of the solutions. She needs to identify the unknown sample. Explain how the teacher can identify the unknown sample.
Answer: By performing the flame test
Explanation:
The flame test can be performed by the teacher to visually identify the substance in the solution. The metals give a characteristic color on burning. The heat of the flame causes the excitation of the electrons present in the metal ions this leads to release of energy along with the emission of visible wavelength of light. This visible light can be observed by human eye. For example, the copper produces the blue color in flame, barium gives green flame, and sodium gives yellow flame.
What do the colors represent?
Answer:
Dark Blue: Symbolizes integrity, knowledge, power, and seriousness. Blue: Peace, tranquility, cold, calm, stability, harmony, unity, trust, truth, confidence, conservatism, security, cleanliness, order, loyalty, sky, water, technology, depression, appetite suppressant.
