A.92 all Uranium atoms contain the same amount of protons
Answer:
C )
Explanation:
Controlled scientific experiment tests scientific assumption (hypothesis), under controlled conditions.
In controlled scientific experiment, alters the test variable (independent variable) and observes the effects on the outcome variable (dependent variable).
Eg : Studying impact of sunlight on plant's group, where former independent variable is altered & its effects on dependent outcome variable is observed.
Answer:
a) formula for citric acid is - C6 H8 o7
b) lime water turns opaque after adding co2 due to the formation of calcium carbonate.
c) reaction 3 is displacement reaction where a high reactive metal displace a less reactive from its salt solution.
d) reaction 1) is combination reaction where two reactant combines to give a single product whereas reaction 2) is decomposition reaction where a single reactant splits into more that 1 products.
CH₃CH₂OCH₂ is more soluble in water because it has shorter hydrocarbon chain.
<h3>What is hydrocarbon?</h3>
Hydrocarbon is defined as the compound which contain hydrocarbon and carbon atoms.
The carbon atom attached to each other to form framework and hydrogen atom attach to them in different ways to give different configuration. One of the most popular hydrocarbon compound is diamond.
<h3>Solubility of hydrocarbon in water</h3>
Hydrocarbon is non polar compound whereas water is polar compound. So, hydrocarbon is in soluble in water. But as they have weak intermolecular interactions known as London dispersion forces i.e. Instantaneous dipole-induced dipole interactions.
make them less soluble in water.
Greater the hydrocarbon chain lesser will be the solubility of ketone in water. On the other hand, lesser the hydrocarbon chain greater will be the solubility of ketone in water.
Thus, we concluded that the CH₃CH₂OCH₂ is more soluble in water because it has shorter hydrocarbon chain.
