Answer:

4 hydrogen atoms are attached with the carbon atom in the molecule.

Explanation:

Hydrocarbon molecule is a type of molecule which is composed of hydrogen and carbon atoms. Carbon atom belongs to group 4 in the periodic table which means it has four electrons in its outermost shell or orbit, so for attaining octet rule, carbon atom makes 4 covalent bonds with 4 hydrogen atoms and 4 electrons of hydrogen atom is used by the carbon atom and becomes a stable molecule.

The Brazos River is a major river in Texas. In many parts of the Cross Timbers and Prairies ecoregion, the river has formed tall
musickatia [10]

Answer:

Weather and erosion.

Explanation:

In Geography, weathering is the process of breaking down of rocks, minerals and soil as a result of contact with water, earth's atmosphere, acid, ice, plants and animals. The breaking up of the rocks by weathering weakens it and makes it susceptible to erosion.

Erosion in geography is the movement of rocks and sediments to another place by water, wind and ice.

For instance, In many parts of the Cross Timbers and Prairies ecoregion, the Brazos river has formed tall, steep cliffs in the rock along its banks through the processes of weathering and erosion.

A 20.00-mL sample of a weak base is titrated with 0.0568 M HCl. At the endpoint, it is found that 17.88 mL of titrant was used.
nata0808 [166]

Answer: 0.0508mL

Explanation: Using the basic formula that states: C acid * V acid = C base * V base. we have:0.568 * 17.88 = 20 * C base.

therefore concentration of the base is 1.0156/20 = 0.0508 mL

Urea (CH4N2O) is a common fertilizer that can be synthesized by the reaction of ammonia (NH3) with carbon dioxide as follows: 2N
Lera25 [3.4K]

Answer:

NH3

Explanation:

2NH3(aq)+CO2(aq)→CH4N2O(aq)+H2O(l)

So for two moles of NH3 we need one mole of CO2. So let's count moles for each reagent.

n(NH3)=m(NH3)/M(NH3)=135700/17,03=7968.29 mol

n(CO2)=m(CO2)/M(CO2)=211400/44.01=4803.45 mol

From equation we have to divide n(NH3) by 2 because we need two equivalent per one CO2. That will be 3984.145. So the limiting agent is NH3 because it's not enough of it to react with all CO2
