Is brass a solution:

what stated of matter and how many phases are present when a 5.0 mL sample of oil is mixed with 100.0 mL of water?
A both solid and liquid state= two phases
B two layers of different liquids=two phases
C the liquid state only= one phases
D the solid state only=one phase​

what does cost-effective mean? im kind of confused on cost-effective and time-effective things and i keep getting mixed up :(

Calculate how many moles are in 63.1 grams FeCl3.

A buffer solution was prepared by mixing 50.0 mL of a 0.100 M solution of CH3COOH with 0.500 grams of NaCH3COO. The resulting mixture is diluted to 100.0 mL. What is the pH of the solution

A 1.__________ is a choice among possible alternative actions. Like planning decision-making is a challenge and requires careful consideration for both types of decision namely 2.____________________________ and 3.______________________. For effective planning in today’s dynamic environments. Different techniques and tools must be used, such as 4._________________, 5.______________________________, 6.______________________________, 7.________________________, 8.__________________. All planning types, without exception, make use of forecasting. Business periodicals publish forecasts such as employment and unemployment rates, increase or decrease of interest rates, stock market data, GNP/GDP data and others. Forecasts used may either be 9._________________, or 10.__________________. Risk or 11._________________________ compel the decision maker to do estimates regarding the possible occurrence of certain outcomes that may affect his or her chosen solution to a problem. All managers and workers/employees in organizations make decision or make choices that affect their jobs and organization they work for, they make decision by going through the 12.__________________________ of the decision-making process suggested by Robbins and Coulter (2009). 13._________________ is a process which begins with problem identification and ends with the evaluation of implemented solutions. 14.________________________ It is change in an attribute, condition, factor, parameter or value that represents crossing a threshold and actuates or initiates a mechanism or reaction that may lead to a radically different state of affairs. 15.________________________ Ideal conditions in deciding problems; these are situations in which a manager can make precise decisions because the results of all alternatives are known.

10) Explain which substance(s) would you expect to be a gas at standard
temperature and pressure (STP).
NI3
BF3
PC13
A) BF3
Its molecules are nonpolar and, therefore, are subject only to
dispersion forces.
B) NI3
Its molecules are polar and possess dipole-dipole interactions
therefore allowing them to exist as a gas.
C) PCL3
Its molecules are slightly polar and, therefore, possess dipole-
dipole interactions. However, they are weak enough to allow it
to exist as a gas.
D) Nlz and BF3
Both molecules are very light in mass. Therefore, they have
weak dispersion forces which causes them to be attracted very
weakly and exist as a gas.

A sample of crude sodium iodide was analysed by the following rection.
I- + SO42- → I2 + H2S (unbalanced)

a)Determine the oxidation number for S in SO42-.

b)The above reaction requires a basic medium. Write the balanced chemical equation. [6 marks]​
