Hey there!
Great question=)

Answer: Contrast-Same chemical composition. Granite is intrusive, when rhyolite is extrusive!
Compare-Different cooling rates.

Answer:

Explanation:

Hello,

In this case, we say that rhyolite is very closely related to granite, nonetheless rhyolite has a larger a mount of finer crystals than granite, which are as tiny as they are not possible to be seen by a simple look with out eyes. Moreover, rhyolite is an extrusive igneous rock that was formed by cooling down more rapidly than granite which provide it a glassy glance. Additionally, rhyolite is made up of quartz, feldspar, mica, and hornblende.

On the other hand, the granite is a shiny-like igneous rock with visible grans by a simple look (unlike rhyolite). It is formed when a sluggish crystallization of magma is carried out underground. It is majorly made up of quartz and feldspar with traces of mica, amphiboles, and other minerals.

Best regards.

The aldol condensation involves nucleophilic attack of an enolate to a carbonyl. Use the pop-up menus to identify the total numb

Sindrei [870]

Aldol condensation involves the reaction of an acid or base with a carbonyl group producing a nucleophile that attacks another carbonyl compound to yield a β-hydroxyaldehyde or β-hydroxyketone compound.

<h3>What is aldol condensation?</h3>

The aldol condensation is a reaction in organic chemistry in which there is a reaction between an acid or base and a carbonyl group which then serves as the nucleophile that attcks a second carbonyl to yield a β-hydroxyaldehyde or β-hydroxyketone compound.

The aldol condensation may be acid catalysed or base catlysed. The question is incomplete hence the complete mechanimsms can not be decuced.

Deuterium is a relatively uncommon form of hydrogen, but can be created from water.

Heavy hydrogen commonly known as deuterium
stable isotopes of hydrogen
gets its name from the Greek word deuterons means second.
has only one proton and one neutron
nucleus of the hydrogen's deuterium atom is known as a deuteron containing one proton and one neutron.
Deuterium forms chemical bonds that are stronger than regular hydrogen
gas deuterium is colorless
Deuterated water is used in Magnetic Resonance Spectroscopy.
used in the determination of the isotopologue of various organic compounds.

Omg pls help i dunno what the frick frack this is

snow_lady [41]

Answer:

1. Mass of KCl produced = 774.8 g of KCl

2. Mass of KNO₃ produced = 13.837g

3. Moles of NaOH made = 0.846 moles

4. Moles of LiCl produced = 0.846 moles

5. Moles of CO₂ produced = 207.6 moles

Explanation:

1. From the equation of reaction, 1 mole of ZnCl₂ produces, 2 moles of KCl.

5.02 moles of ZnCl₂ will produce, 2 × 5.02 moles of KCl = 10.4 moles of KCl

Molar mass of KCl = (39 + 35.5) g/mol = 74.5 g/mol

10.4 moles of KCl = 10.4 × 74.5 g

Mass of KCl produced = 774.8 g of KCl

2. Mole ratio of KNO₃ and KOH = 1:1

O.137 moles of KOH will produce 0.137 moles of KNO₃

Molar mass of KNO₃ = 101 g/mol

Mass of KNO₃ produced = 0.137 × 101 g = 13.837g

3. Molar mas of Ca(OH)₂ = 74.0 g

Moles of Ca(OH)₂ in 31.3 g = 31.3/74.0 = 0.423 moles of Ca(OH)₂

Mole ratio of NaOH and Ca(OH)₂ in the reaction = 2 : 1

Moles of NaOH made = 2 × 0.423 = 0.846 moles

4. Molar mass of MgCl₂ = 95.0 g

Moles of MgCl₂ in 40.2 g = 40.2/95.0 = 0.423 moles

From the reaction equation, mole ratio of MgCl₂ and LiCl = 1:2

Moles of LiCl produced = 2 × 0.423 = 0.846 moles

5. From the equation of reaction, 1 mole of C₆H₁₀O₅ produces 6 moles of cO₂

34.6 moles of C₆H₁₀O₅ will produce 34.6 × 6 moles of CO₂

Moles of CO₂ produced = 207.6 moles

Question 6

Oksanka [162]

Answer:

Acid/String Electrolyte

Explanation:

Litmus paper turning red means it is an acidic solution. A pH of more than 7 is Base while pH of less than 7 is an acid. Since the pH is 2, less than 7, it s is an acid. Since it has a high electrical conductivity, it must be a strong Electrolyte.

how many grams of oxygen gas are needed to produce 10.0 grams of carbon dioxide according to the balanced equation of CH4

Alinara [238K]

Molar mass of :

O2 = 16 * 2 = 32 g/mol

CO2 = 12 + 16 * 2 = 44 g/mol

<span>Balanced chemical equation :
</span>
1 CH4 + 2 O2 = 1 CO2 + 2 H2O
↓ ↓
2 moles 1 mole

2* 32 g O2 ----------> 1* 44 g CO2
x g O2 ------------> 10.0 g CO2

44 x = 2 * 32*10.0

44 x = 640

$x = \frac{640}{44}$

$x = 14.54 g$ of O2
