What type of rock is this?
Answer:
I'm gonna say igneous
Explanation:
The texture looks rough and the rock looks like it's composed of different types of minerals making it an igneous rock
I hope this helps :)
Answer: Igneous
Explanation: Igneous rock, or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic. Igneous rock is formed through the cooling and solidification of magma or lava. The magma can be derived from partial melts of existing rocks in either a planet's mantle or crust.

Yule logs are commercially available that burn with a red and green flame. What two chemicals could produce this effect?
Answer:
Strontium chloride: Makes a red flame.
Strontium sulfate: Makes a green flame.
Copper salts (such as copper sulfate or copper chloride) and barium salts (such as barium chloride or barium nitrate) can produce a red and green flame when burned.
The colors of flames are often determined by the presence of specific chemicals or elements that emit characteristic wavelengths of light when heated. In the case of red and green flames, copper and barium salts are commonly used.
Copper salts, particularly copper sulfate or copper chloride, can produce a green flame when burned. This is due to the emission of specific wavelengths of green light by excited copper ions in the flame.
Barium salts, such as barium chloride or barium nitrate, can produce a red flame when burned. The red color is caused by the emission of specific wavelengths of red light by excited barium ions in the flame.
When these two chemicals are combined in a yule log or firework formulation, they can create a visually appealing display of red and green flames. The copper and barium ions are heated and excited by the flame, releasing their characteristic colors of light. It is important to note that the production of colored flames should be done with caution and adherence to safety guidelines to ensure proper handling and disposal of chemicals.

Waves often bounce off objects such as water. What is this form of wave movement called?
A.
reflection
B.
refraction
C.
interference
D.
resonance
Answer:
Reflection
Explanation:
Reflection is when something is bounced off something else such as light bouncing off objects therefore the waves are reflecting. Also when light bounces off of a surface it reflects rather than refraction which refers to the light bending as it enters a new medium

Impurities that evaporate easily and travel with the water vapor are not removed when using this type of distillation. Explain the reason for this.
Answer:
Please add as brainlist
Explanation:
Distillation is the process of separating the components or substances from a liquid mixture by using selective boiling and condensation. Distillation may result in essentially complete separation (nearly pure components), or it may be a partial separation that increases the concentration of selected components in the mixture. In either case, the process exploits differences in the relative volatility of the mixture's components. In industrial applications, distillation is a unit operation of practically universal importance, but it is a physical separation process, not a chemical reaction.
True or false
Equal forces acting on one object in opposite directions are called balanced forces
Answer:
True
Explanation:
Forces, equal in magnitude and opposite in direction, and cancel each other out are called Balanced Forces.
Balanced Forces DO NOT cause any change in the velocity of the object, but the Object may correspond to a change in shape or size.
Example :
Blasting a balloon by compressing it tightly with both hands, roughly with an equal force, is a practical example of Balanced Forces. In this case, the balloon before the burst stays at a state of rest and same after the burst. But the burst or the compression, causes a change in the shape of the balloon.

A long thin sample of a substance is easily bent. When the substance is placed in a n electric circuit and the switch is closed, and LED light turns on. What type of bonding holds the particles of the substance together?
Answer:
A metallic bonding holds the particles of the substance together
Explanation:
The unknown substance is a metal:
It is easily bent: This means it is ductile, as it is the case with a thin metallic metallic wire."When the substance is placed in a n electric circuit and the switch is closed, and LED light turns on." This means it easily conducts electricity. Metals are good conductors.a metal worker uses a cutting torch that operates by reacting acetylene gas, C2H2(g), with oxygen gas, O2(g), as shown in the unbalanced equation below: C2H2(g)=O2(g)= CO2(g) = H2O(g) = heat determine the mass of 25 moles of acetylene (gram-formula mass = 26 g/mol
Answer:
650 grams
Explanation:
Given that acetylene gas reacts with oxygen to produce caobon dioxide, water and heat and the unbalnced equation is
[tex]C_2H_2(g)+O_2(g) \rightarrow CO_2(g) + H_2O(g)+ heat[/tex]
Gram-formula mass of [tex]C_2H_2= 26[/tex] g/mol
So, mass of 1 mole of acelylene is 26 grams
Therefore, mass of 25 moles of acelylene=25x26=650 grams
Hence, the mass of 25 moles of acelylene is 650 grams
The mass of 25 moles of acetylene has been 0.65 kg.
Moles are the count of a number of molecules in an entity and the mass based on the formula mass. 1 mole of a substance has [tex]\rm 6.023\;\times\;10^2^3[/tex] molecules.
The moles can be calculated as:
Moles = [tex]\rm \dfrac{weight}{molecular\;weight}[/tex]
Given, mole of acetylene = 25 mol
molecular mass of acetylene = 26 g/mol
Mass of acetylene = moles [tex]\times[/tex] molecular weight
Mass of acetylene = 25 [tex]\times[/tex] 26
Mass of acetylene = 650 grams
1000 grams = 1 kg
650 grams = 0.65 kg.
The mass of 25 moles of acetylene has been 0.65 kg.

4 points

Answer: 2
Explanation:
To calculate the moles :
[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]
[tex]\text{Moles of} Fe_3O_4=\frac{275g}{233.5g/mol}=1.18moles[/tex]
[tex]3Fe(s)+4H_2O(g)\rightarrow Fe_3O_4(s)+4H_2(g)[/tex]
According to stoichiometry :
1 mole of [tex]Fe_3O_4[/tex] are produced by = 4 moles of [tex]H_2O[/tex]
Thus 1.18 moles of [tex]Fe_3O_4[/tex] will be produced by=[tex]\frac{4}{1}\times 1.18=4.72moles[/tex] of [tex]H_2O[/tex]
Mass of [tex]H_2O=moles\times {\text {Molar mass}}=4.72moles\times 18g/mol=85.0g[/tex]
Thus 85.0 g of [tex]H_2O[/tex] will be required and 2 steps are required to get the answer.
